ReducingToothSensitivitywillDependontheCause

If you're one of over 30% of Americans who wince in pain when eating and drinking certain foods and beverages, you may have tooth sensitivity. Although there are a number of possible causes, the most common place to look first is tooth dentin.

Lying just under the enamel, dentin consists of tiny tubules that transmit sensations like pressure or temperature variation to the nerves of the inner pulp. The enamel, the gums and a covering on the roots called cementum help dampen these sensations.

But over-aggressive brushing or periodontal (gum) disease can cause the gums to shrink back (recede) and expose the dentin below the gum line; it can also cause cementum to erode from the roots. This exposure amplifies sensations to the nerves. Now when you eat or drink something hot or cold or simply bite down, the nerves inside the dentin receive the full brunt of the sensation and signal pain.

Enamel erosion can also expose dentin, caused by mouth acid in contact with the enamel for prolonged periods. Acid softens the minerals in enamel, which then dissolve (resorb) into the body. Acid is a byproduct of bacteria which live in dental plaque, a thin film of food particles that builds up on teeth due to poor oral hygiene. Mouth acid may also increase from gastric reflux or consuming acidic foods or beverages.

Once we pinpoint the cause of your tooth sensitivity we can begin proper treatment, first and foremost for any disease that's a factor. If you have gum disease, we focus on removing bacterial plaque (the cause for the infection) from all tooth and gum surfaces. This helps stop gum recession, but advanced cases may require grafting surgery to cover the root surfaces.

You may also benefit from other measures to reduce sensitivity: applying less pressure when you brush; using hygiene products like toothpastes that block sensations to the dentin tubules or slow nerve action; and receiving additional fluoride to strengthen enamel.

There are effective ways to reduce your tooth sensitivity. Determining which to use in your case will depend on the cause.

EvenCelebritiesLikeJenniferLawrenceArentImmuneFromBadBreath

Exchanging passionate kisses with big-screen star Jennifer Lawrence might sound like a dream come true. But according to Liam Hemsworth, her Hunger Games co-star, it could also be a nightmare… because J.Law’s breath wasn’t always fresh. “Anytime I had to kiss Jennifer was pretty uncomfortable,” Hemsworth said on The Tonight Show.

Lawrence said the problem resulted from her inadvertently consuming tuna or garlic before the lip-locking scenes; fortunately, the two stars were able to share a laugh about it later. But for many people, bad breath is no joke. It can lead to embarrassment and social difficulties — and it occasionally signifies a more serious problem. So what causes bad breath, and what can you do about it?

In 9 out of 10 cases, bad breath originates in the mouth. (In rare situations, it results from a medical issue in another part of the body, such as liver disease or a lung infection.) The foul odors associated with bad breath can be temporarily masked with mouthwash or breath mints — but in order to really control it, we need to find out exactly what’s causing the problem, and address its source.

As Lawrence and Hemsworth found out, some foods and beverages can indeed cause a malodorous mouth. Onions, garlic, alcohol and coffee are deservedly blamed for this. Tobacco products are also big contributors to bad breath — which is one more reason to quit. But fasting isn’t the answer either: stop eating for long enough and another set of foul-smelling substances will be released. Your best bet is to stay well hydrated and snack on crisp, fresh foods like celery, apples or parsley.

And speaking of hydration (or the lack of it): Mouth dryness and reduced salivary flow during the nighttime hours is what causes “morning breath.” Certain health issues and some medications can also cause “dry mouth,” or xerostomia. Drinking plenty of water can encourage the production of healthy saliva — but if that’s not enough, tell us about it: We may recommend switching medications (if possible), chewing xylitol gum or using a saliva substitute.

Finally, maintaining excellent oral hygiene is a great way to avoid bad breath. The goal of oral hygiene is to control the harmful bacteria that live in your mouth. These microorganisms can cause gum disease, tooth decay, and bad breath — so keeping them in check is good for your overall oral health. Remember to brush twice and floss once daily, stay away from sugary foods and beverages, and visit the dental office regularly for checkups and professional cleanings.

So did J.Law apologize for the malodorous makeout session? Not exactly. “[For] Bradley Cooper, Christian Bale, yeah, I’ll brush my teeth,” she laughed.

Hemsworth jokingly agreed: “If I was kissing Christian Bale I probably would have brushed my teeth too. With you, it’s like, ‘Eh. Whatever.’”
