3 Reasons Why Your Teeth Are Sensitive

Posted on: 27 August 2017

It's normal to have temporary sensitivity in your teeth now and then, but if you have sensitive teeth all of the time, then it is an indication that something is wrong. Sensitivity to hot and cold foods and sugar can make eating uncomfortable, and it can also make you want to avoid some of your favorite foods. Anti-sensitivity toothpaste can help make things more comfortable, but what you really should do is get to the cause of the problem. Here are three reasons why your teeth are sensitive and some of the ways you can reduce or eliminate the problem.

Receding Gums

Receding gums are when the gums shrink back and expose some of the root of the tooth. Though it is more common with older people, any type of gum neglect or disease can cause your gums to recede at any age. The root of the tooth is sensitive, especially when it is first exposed, particularly with cold foods and sweets. The best thing to do in this case is practice good oral hygiene from the beginning to keep recession at a minimum. If your gums have already receded, then you may want to opt for surgery to restore the missing gum material.

Your Tooth is Cracked

You could have a crack in your tooth without even knowing it as they're difficult to see with the naked eye. If you suddenly start feeling pain and sensitivity when eating hot or cold food, you don't have any existing fillings, and your tooth looks otherwise fine, then it could be cracked. If you have a filling, then it's possible that your filing is cracked or your tooth has decayed around it and caused a gap underneath. You might even have an undiagnosed cavity or need a root canal.

You Brush Too Hard

You may feel like you're helping your teeth by using hard bristles or a strong strokes, but brushing this way can actually wear down tooth enamel and increase sensitivity. If you wear the enamel down enough, it exposes the dentin which is extremely sensitive. Hard brushing also encourages gum recession problems. Instead, use a brush with soft bristles and use gentle, up and down strokes.

Frequent or constant tooth sensitivity is nothing to be ignored and should be addressed with your dentist. Many issues that cause tooth sensitivity can be reduced or prevented with regular dental examinations and cleanings in addition to good hygiene. If your teeth are sensitive, especially if they become sensitive in a short time, then see your dentist right away to determine the cause.
