Sensitive Teeth

Sensitive Teeth

Many of us say we have "sensitive teeth." We usually mean that we feel twinges of pain or discomfort in our teeth in certain situations. These may include:
  • Drinking or eating cold things
  • Drinking or eating hot things
  • Eating sweets
  • Touching the teeth with other teeth or the tongue
There are two types of tooth sensitivity:Dentinal sensitivity occurs when the dentin (middle layer) of a tooth is exposed. Normally, the dentin is covered by enamel above the gumline and by cementum below the gumline. Dentin contains tiny openings called tubules. Inside each tubule lies a nerve branch that comes from the tooth's pulp (the nerve center of the tooth). When the dentin is exposed, cold or hot temperature or pressure can affect these nerve branches. This causes sensitivity.Dentin becomes exposed when the outer protective layers of enamel or cementum wear away. This can affect one or more teeth. Some causes of dentin exposure include:
  • Brushing your teeth too hard. This can wear away the enamel layer.
  • Poor oral hygiene. This may allow tartar to build up at the gum line.
  • Long-term tooth wear
  • Untreated cavities
  • An old filling with a crack or leak
  • Receding gums that expose the tooth's roots. Receding gums often are caused by periodontal diseases or by brushing too hard.
  • Gum surgery that exposes a tooth's roots
  • Tooth whitening in people who have tooth roots that already are exposed
  • Frequently eating acidic foods or drinking acidic liquids
Pulpal sensitivity is a reaction of the tooth's pulp. The pulp is a mass of blood vessels and nerves in the center of each tooth. Pulpal sensitivity tends to affect only a single tooth. Causes include:
  • Decay or infection
  • A recent filling
  • Excessive pressure from clenching or grinding
  • A cracked or broken tooth
If you feel a sharp pain upon biting, you may have a broken or cracked filling. Pain when you release a bite is a sign of a cracked tooth.

Both dentinal and pulpal sensitivity usually involve reactions to temperature or pressure. Sensitivity to cold drinks or foods is the most common symptom. Less often, the teeth are sensitive to hot temperatures. If a single tooth becomes sensitive to heat, the tooth's nerve is dying. In this case, root canal treatment is necessary.

Your dentist will look at your dental history and will examine your mouth. You also will need X-rays to show if there is decay or a problem with the nerve. The dentist will ask about your oral habits. Grinding or clenching your teeth can contribute to sensitivity. Your dentist also will look for decay, deep fillings and exposed root surfaces. He or she may use an explorer — a metal instrument with a sharp point— to test teeth for sensitivity. A tooth may be sensitive to cold for several weeks after you get a filling. The metals in amalgam (silver) conduct the cold very well, transmitting it to the pulp. Bonded (tooth-colored) fillings require etching the tooth with acid before the filling is placed. In some cases, this etching removes enough enamel to make the tooth sensitive. However, advances in bonding now make it less likely to cause tooth sensitivity.
Your dentist or endodontist can do tests to see if you need root canal treatment.

If your tooth becomes sensitive after a deep filling is placed, the problem may go away in several weeks. Sometimes the filling is too high. That puts too much pressure on the tooth when you bite down. Your dentist can reduce the height of the filling. If the sensitivity does not go away over time, the tooth probably needs a root canal. Sensitivity in more than one tooth may disappear in a short time or it may continue. It depends on the cause of sensitivity. Every case is different. Some people have sensitive teeth for only a month or two. Others have the condition for years.

space placeholder.Prevention

Dentinal sensitivity — You might be able to reduce your chances of dentinal sensitivity by:
  • Brushing twice a day and flossing daily
  • Using a soft or ultrasoft toothbrush and brushing gently up and down, rather than side to side
  • Using a fluoride toothpaste and mouth rinse
  • Using a toothpaste that provides protection against sensitivity
  • Getting treatment for grinding or clenching your teeth (bruxism)
Pulpal sensitivity — If a tooth needs root canal treatment, there is no good way to prevent pulpal sensitivity other than to get the needed treatment. Delaying root canal treatment is not recommended. It may result in further problems.

Dentinal sensitivity is quite treatable, whatever the cause. Your dentist or dental hygienist will clean your teeth. If your teeth are too sensitive to be cleaned, your dentist may use a local anesthetic or nitrous oxide before the cleaning.
After a cleaning, your dentist may apply a fluoride varnish to protect your teeth. This temporarily reduces sensitivity. It also strengthens your teeth. Your dentist may apply an in-office treatment for sensitivity. These products block the openings (tubules) in dentin and reduce sensitivity. A newer approach is to use a dental laser. The laser treatment also alters the tubules to reduce sensitivity. Using fluoride toothpastes and fluoride mouth rinses at home will help to reduce sensitivity. You also can buy toothpastes just for sensitive teeth. Talk to your dentist about which fluoride rinses you should use. Some over-the-counter rinses are acidic. Others are not. You should choose a fluoride mouth rinse that uses neutral sodium fluoride. Pulpal sensitivity will be treated with a root canal if the tooth's nerve is damaged or dying. Your dentist will remove the nerve and place a non-reactive substance (gutta percha) in the space where the nerve was. The tooth no longer will have a continuous barrier of enamel to protect it. Therefore, it will be restored with either a composite filling or a crown. To reduce pain due to grinding or clenching, the dentist will make a plastic night guard. Use the guard while you sleep.

A Friend For Life - Navigating The World Of Soft Toys

A Friend For Life - Navigating The World Of Soft Toys

There's no denying that, when chosen correctly, a soft toy can remain an important part of a child's life right up and throughout their adult years. Some soft toys, in fact, will end up being passed on through families and into new generations. So it makes sense that you spend a little longer choosing which soft toy is right for the person you're buying it for, as it will almost definitely be around for a very long time.

First things first, make sure that the soft toy you choose is safe for small children. You need to look out for a mark of certified quality, as well as check out the workmanship – all eyes, noses and parts must be securely fastened, seams must be sewn tightly shut. It wouldn't do to have your soft toy disintegrating on the first hug now, would it?
 Secondly, think carefully about which soft toy character you want to buy. Is it going to be something as timeless as a teddy-bear, as simple as a sock puppet or something bang up-to-date, such as a Moshi Monster? Whichever you decide to choose, be aware that it'll be sticking around for a good while – do you really think the latest craze will last the sands of time?
 Thirdly, do you want a simple soft toy, or do you want your plush toy to pack some extra punch? Plenty of soft toys available now offer everything from sound effects (everybody loves a chatterbox!) to scent-sations (it isn't a teddy-bear unless it smells like strawberries!), so you can get a hi-tech softy or an old classic.

Fourthly, think about the person you are buying the soft toy for. Is it a new-born baby, looking for a simple comforter? Then you'll be better off with a traditional bear. Is it an older baby, learning to walk and talk? Then try an interactive soft toy to help stimulate their learning and help them through their development. Older children will probably have a strong idea of what they want for themselves, whereas adults usually prefer a soft toy with sentimental value – think retro and think simple.
 When chosen correctly, soft toys can have a hugely beneficial effect. Hugging a plush toy releases the "attachment hormone" oxytocin, which helps to slow the heart rate, soothe breathing, lower blood pressure and reduce the effects of stress. Result! That makes the cuddly creation a bona fide soothing agent. What could be better than that?

What's So Great About Kissing?


What's So Great About Kissing?

A serious, tongue-tangling kiss triggers a whole spectrum of physiological processes that can boost your immunity and generally spruce up that body you work so hard to keep attractive.



Face it -- a great kiss makes the world dissolve, makes us dizzy with desire.
"Kissing is passion and romance and what keeps people together," says Michael Cane, author of The Art of Kissing, who "lectures" on kissing at colleges around the country.

"Women say they can tell if a relationship is going to work after the first kiss, after the first night of kissing," he says. "They just get a feeling, an intuition."
And while kissing may feel oh-so-good, it also has health benefits, too. It triggers a whole spectrum of physiological processes that boost your immunity and generally spruce up that body you work so hard to keep attractive.

Kiss Me, You Fool

Among the benefits of a good wet one: That extra saliva washes bacteria off your teeth, which can help break down oral plaque, says Mathew Messina, DDS, a private practice dentist in Fairview Park, Ohio, and consumer advisor for the American Dental Association. "Still, I would not go around advocating kissing after meals instead of brushing," he says.
A serious, tongue-tangling French kiss exercises all the underlying muscles of the face -- which some say could keep you looking younger, and certainly looking happier.
Kissing might even help you lose weight, says Bryant Stamford, PhD, professor and director of the health promotion center at the University of Louisville. "During a really, really passionate kiss, you might burn two calories a minute -- double your metabolic rate," he says. (This compares to 11.2 calories per minute you burn jogging on a treadmill.)
When you give sugar, you actually burn sugar. Sex sparks a good calorie burn, Stamford says, especially "if you're passionately involved, thrashing around. If things were really hot and heavy, you might be looking at a caloric expenditure similar to a brisk walk."
But don't confuse great sex with a cardiovascular workout, he says.
"People tend to have the misconception that anything that raises your heart rate has the same effect as jogging, so it must be good for fitness. Not true," he says. "Anything can get your heart racing ... that's just adrenaline."

Tension relief -- that's what good lovin' brings, says Stamford. "Sex and love are probably the Rodney Dangerfield of stress management. Because of all the negative energy we take in during the day, it's a very positive benefit."
All in all, kissing and everything it engenders keeps us going strong, living long, says Stamford. "The process of being active -- and that can include kissing, sex, and any other whole-body activities -- that's what keeps you healthy."
Sex, sensuality, and sensual touch have profound effects on well-being, says Joy Davidson, PhD, psychologist and clinical sexologist in Seattle, and former columnist for an online column called "Underwire."
"Kissing is an exciting excursion into the sensual," Davidson tells WebMD. "If we happen to be connecting with someone we care about, it produces a sense of well-being and a kind of full-bodied pleasure."
Kissing is also "a sensual meditation," she says. "It stops the buzz in your mind, it quells anxiety, and it heightens the experience of being present in the moment. It actually produces a lot of the physiological changes that meditation produces."
And while kissing may be nature's way of "opening the door to the sexual experience," she says, "it also has all that lusciousness that we need to pull us out of the mundane and the ordinary and take us into moments of the extraordinary."

Birds, Bees, and More

Birds do it -- tap their bills together, that is.
"We don't know if bees do it," says Helen Fisher, PhD, professor of anthropology at Rutgers University in Newark, N.J., and author of several books, including The Sex Contract and Anatomy of Love. Romantic love is her research specialty.
"All kinds of animals kiss," says Fisher. "Insects will stroke each other with a leg, or stroke another's abdomen. Even turtles, moles, and cats rub noses. Dogs lick each other's faces. Elephants put their trunks in another elephant's mouth."
When chimpanzees kiss, "it's with a deep French kiss," she says. "They do it for all kinds of reasons -- there's social kissing, kissing to relieve tension, to express friendship, to make up after an argument. Two males will kiss, two females will kiss, a mother and child will kiss on the lips. They don't choose mates; it's whomever they're interacting with."
Kissing is a very investigatory process, Fisher explains.
"By the time you're kissing someone, you're right up next to them, you are in their personal space," she says. "That in itself means you have trusted them. You're also learning quite a bit about them -- you touch them, smell them, taste them, see the expressions on their face, learn something about their health status, learn a great deal about their intentions."
The brain contains "a huge amount of receptors devoted to picking sensations from the lips," Fisher says. "When people have been stabbed in the back, they often don't know it. They think someone has pounded them with their fist, because there aren't many receptor sites for nerve endings."
Why? All these sensors aid our survival. They direct a baby toward milk; they helped our ancestors -- for millions of years -- to discern whether their food was poisonous or not. "The mouth is absolutely essential to survival -- everything passes through there, and if it's the wrong thing, you're cooked," she says.
"The receptors on the lips are incredible," she tells WebMD. "I've heard hookers say they would rather copulate with somebody than kiss them because the intensity of kissing somebody is so meaningful. There's tremendous intimacy. ... Even the genitals do not have the sensitivity that the lips have."

The Bonding Power of Locking Lips

For man and animals, kissing is a bonding behavior, she says. "There are all kinds of social reasons that humans and animals kiss, and they don't all have to do with sex. Most cultures in the world do kiss sexually. [But some] peoples in South America, some in the Himalaya Mountains, do not kiss. They find it revolting to exchange saliva."
Kissing also engenders touch, often called "the mother of the senses, because of its power," says Fisher. "We know that massaging someone produces increased levels of oxytocin, which is a calming hormone. So there's every reason to think kissing is extremely calming, if you know the person well, or extremely stimulating if you are in love with somebody."
Studies of rodents -- voles, specifically -- have shown that oxytocin makes a mother vole become attached to its offspring, says Larry Young, PhD, professor of psychiatry in the Center for Behavioral Neuroscience at Emory University Medical School in Atlanta.
Whether a guy vole sticks around "afterward" seems to be driven by oxytocin, Young tells WebMD.
Prairie voles are the only vole species that mate for life; their genetic makeup drives them to produce satisfying amounts of oxytocin. On the other hand, mountain voles are loners and breed promiscuously; they produce virtually no oxytocin.
In humans, this translates into the bonding benefits of kissing, foreplay, every bit of touching you do.
Here's a tip: "One of most powerful releases of oxytocin is stimulation of the nipples," Young tells WebMD. It's the same biological mechanism that triggers milk flow during nursing. Sucking triggers oxytocin release, and thus the bond is created.
Humans, interestingly enough, are the only species that includes nipple stimulation in lovemaking, he adds.

Romance, Love -- or Lust?

That rush that sweeps through your body, during those particularly great kisses? Fisher knows it well.
"Kissing is contextual," she says. "A kiss can be wildly sexual, wildly romantic, or it can be deeply gratifying because it's an affirmation of attachment. Kissing somebody for the first time, rather than the 200th or 2,000th time, creates a situation of incredible novelty."
That rush you feel is probably from two natural stimulants -- dopamine and norepinephrine, Fisher says. "They tend to be activated when you get into a novel situation."
Fisher says there are three different stages one typically goes through:
  • lust -- the craving for sexual gratification
  • romantic love -- the feeling of giddiness, euphoria, sleeplessness, and loss of appetite when you meet a new love
  • attachment -- that sense of security you find with a with long-term partner.
"Each of these is associated with different chemical systems in the brain," says Fisher. Sex drive and lust are triggered by testosterone, in both men and women. Dopamine and norepinephrine kick in when romance begins. Oxytocin is a factor in at the attachment phase, bringing the sense of calm and peace you find with "the one."
If you're in the midst of a "mad love affair, it's quite possible you simply feel levels of dopamine, that zing of romantic infatuation," Fisher tells WebMD. "If all you're doing is having a sexual fling with someone you like very well -- but are not in love with and don't feel attached to -- then all you may feel is sex drive, the effects of testosterone."
Unless you're kissing the wrong person, kissing quite likely is good for us, says Fisher.
"I've often thought it would boost the immune system," she says. "If you're sharing your germs with somebody, you're adding to your internal defense system."
Kissing also stimulates the brain, and when the experience is a positive one, "you notice it," she says. "That translates into the euphoria, or the sex drive, or the sense of calm and peace.
"Kissing helps your state of mind," she adds. "Infatuation can be perfectly divine. If you're madly in love with somebody, it's perfectly wonderful to kiss them. It creates incredible intimacy. It boosts self-esteem. It's wonderful to be kissed by somebody."
