Have you ever passed on ice cream because you know it will send a searing pain through your mouth? Has a nice cup of hot coffee ever hurt your teeth? If so, you probably have sensitive teeth. This condition affects at least 45 million Americans. However, just because it’s common doesn’t mean it’s not important to treat. Let’s look at what causes sensitive teeth and how it can be dealt with.
What Causes Tooth Sensitivity?
When the enamel, or the outer layer of the tooth, wears down over time, it can expose microscopic tubules in the layer of dentine underneath. Teeth become sensitive when the cells within these tubules are stimulated. This results in a sharp pain when exposed to hot or cold temperatures.
Cracks in the enamel can also cause tooth sensitivity. Teeth can expand and contract due to extreme changes in temperature. Microscopic cracks can develop over time, so hot or cold sensation may enter the cracks in the tooth and reach the nerve.
Is Tooth Sensitivity a Sign of an Emergency?
Having sensitive teeth doesn’t necessarily mean you should run to your emergency dentist. However, if your teeth remain constantly sensitive for more than three or four days, it might be best to go ahead and schedule an appointment as soon as you can. It might be a sign that you have a cavity or an infected tooth pulp that could mean you need root canal therapy. If not, your dentist may prescribe gel or toothpaste to treat the sensitivity.
How Can I Reduce My Tooth Sensitivity?
There are a few things you can do at home to manage tooth sensitivity, such as:
- Change out your toothpaste. Some toothpastes, particularly those with whitening agents, can increase sensitivity. Swap out your whitening toothpaste with one designed specifically to treat sensitive teeth. Be aware that it can take a few weeks of daily use for this toothpaste to really take full effect.
- Brush gently. Brushing too hard can actually wear down your enamel, leaving you more vulnerable to pain. Also, use a toothbrush with the softest bristles you can find in order to preserve enamel.
- Avoid acidic foods and drinks. These kinds of food and drinks, such as cheese, marinara sauce, and citrus fruits, can irritate sensitive teeth. Limit these items to prevent pain.
Tooth sensitivity is not the end of the world. Often it can be treated. When in doubt, see your emergency dentist and ask them what the best course of action would be.
