Dentin hypersensitivity, colloquially known as sensitive teeth, affects more than 40 million Americans. It is caused when dentin, which is the middle layer of the tooth, becomes exposed by thinning enamel. The nerves and cells within the tooth become inflamed when irritants come in contact with the tooth surface. Cold is not the only source of irritation, either. Sweets, sour foods, plaque, and even the open air itself can cause discomfort and pain.
As noted above, dentin hypersensitivity is caused by the thinning of the tooth protective outer layer, known as enamel. Enamel is very hard compared to dentin and the pulp that surrounds the tooth root. However, it is also very thin, and it can be worn away by a number of causes.
As people age, enamel thins from wear and tear and the natural deterioration that affects the whole body.
Brushing too hard near the gumline can damage enamel. Bruxism, or tooth grinding, will wear down enamel very quickly Tooth decay destroys enamel and forms cavities.
Periodontal disease causes gums to recede from the teeth and contributes to decay of enamel. Damaged enamel can be a side effect of periodontal surgery. Chemicals or digestive acids can damage enamel.
One or more of these factors will inevitably result in the same outcome exposed dentin and hypersensitivity to various stimuli. If you begin to feel discomfort or pain when you brush your teeth, you need to call your dentist and schedule treatment.
Any discomfort or pain while eating should also be professionally addressed because if you wait too long, you will find yourself changing your diet in unhealthy ways to avoid the pain.
Failure to have your teeth periodically cleaned can also contribute to decay, gum disease, and plaque buildup.
Fortunately, dentin hypersensitivity is easy for a trained dental professional to correct. There are several treatment methods that we can use. The option we recommend is always based upon the severity of the case and the patients prior dental history. A few of these treatments are described as follows:
In a relatively mild case, often all that is needed is a change in toothpaste. These desensitizing toothpastes are made just for sensitive teeth. They contain chemicals that block pain signals in the nerves inside of teeth. It takes a few days for the toothpaste to take effect, but after that, the relief is consistent.
If the tooth enamel is significantly damaged or eroded, we may recommend fluoride treatments. Fluoride has the ability to remineralize the damaged enamel. It actually binds to the surface of teeth and strengthens it, minimizing discomfort in the process. Fluoride can be applied in the dental office or prescribed as an at-home treatment.
If the enamel has been destroyed in places, we will use dental sealants or cosmetic dental bonding resin are sometimes to treat dentin hypersensitivity. These substances coat the teeth and block irritants from penetrating the surface.
In light of how simple and cost-friendly these treatments are, does it not make sense to see a dentist the minute you notice consistent discomfort or pain while eating or drinking?
Ignoring the condition will certainly lead to tooth decay and possible periodontal disease. Avoid complications and future costs by scheduling an appointment today.
