Teeth Whitening Sensitivity Causes and How to Treat Them

Over–the–counter teeth whitening procedures have grown increasingly popular due to their ease of use and relatively lower price compared to in–office and professional teeth whitening procedures. Unfortunately, despite the obvious good effects of having whiter teeth, bleaching also causes sensitivity – due to chemical reactions in the enamel. Dentists offer variety of solutions to help solve this problem.

Teeth become sensitive because of the bleach formula that is applied to both the teeth and gums. Bleach is a powerful solution that can cause sensitivity when not applied properly or when applied excessively. This is one of the reasons why the procedure is not recommended for early teenagers and pregnant women. The hydrogen peroxide solution on teeth whitening products can affect the enamel and soft tissues in the gums and digestive tract.

While dental sensitivity is a common issue that can affect almost anyone, severity of reaction depends on three key things: genetics, bleach stability and solution strength, and acidic reaction. Now, how exactly does sensitivity occur? Inside every tooth are millions of microscopic dentinal tubules containing nerve endings that extend from the nerve inside the tooth to its surface. These tubes contain fluid inside and when moved, cause sensitivity. Minerals from saliva normally plug up these holes. When these are dissolved by the bleaching agent, the liquids inside the teeth move, causing sensitivity.

Teeth sensitivity can be a negative aspect, but professional teeth whitening Los Angeles treatments, often done in clinics with high quality products, can reduce this side effect to a minimum. Because sensitivity is a big issue, there has been a lot of interest in solving the issue, or at least developing affordable and reliable ways to help minimize pain and discomfort.

Desensitizing agents are now found in most teeth whitening Los Angeles solutions. These can also be used as medications for those suffering with sensitive teeth, even without undergoing whitening procedures. Fluoride is probably one of the most commonly used desensitizing agents. It acts on one’s dentinal tubes to reduce their size, minimizing fluid movement within. Potassium nitrate is another popular compound for desensitizing. It works on the center of your tooth and has a numbing action that can reduce discomfort.

Discuss sensitivity before undergoing tooth whitening Los Angeles treatments. If you choose over–the–counter strips and gels, avoid putting excessive amounts in your mouth and gums. Always follow directions thoroughly and consult with your dentist if you experience pain after using such products.
