Why Are My Teeth Sensitive All of A Sudden?

Minimal teeth sensitivity might be typical but severe pain with everyday activities is a sign that something is wrong and needs immediate addressing.

Unfortunately, sudden teeth, gums, and jaw pain are prevalent in most adults.

The most attributing cause to this is tooth sensitivity or internal damage. That is either a cracked or infected tooth.

The good news is that there are proven strategies to alleviate and get rid of tooth pain. But first, let’s delve into the possible causes of teeth sensitivity:

1. Gum Recession

Gum tissues begin to wear, exposing the roots of your teeth. Gum recession leaves sections of the tooth exposed and unprotected, triggering sensitivity.

Even worse, it leaves you vulnerable to gum diseases and other infections. Gum recession and gum disease ( gingivitis) cause sensitive teeth.

2. Damaged Enamel

Enamel or dentin erosion is a significant cause of tooth sensitivity. Enamel is the outermost tooth layer that protects the inner sensitive dentin.

When enamel begins to wear off, it exposes the underneath dentine, causing pain and sensitivity.

Acidic food and liquids are the leading cause of enamel erosion.

If you constantly consume acidic foods and drinks such as apples, citrus fruits, sodas, fruit drinks, juices, and sugary foods, you are at a high risk of enamel erosion. It gets worse if you don’t maintain oral hygiene.

3. Sudden Hot Or Cold Temperature

Eating or drinking extremely hot or cold food suddenly can affect the nerves and causes hypersensitivity of teeth.

4. Tooth Cavity

Tooth cavity is a very common reason to cause sensitivity in your teeth. Bacteria can attack your teeth due to the presence of leftover food granules on your teeth.

This causes the cavity and the nerves to get exposed and, thus, can cause teeth sensitivity.

5. Grinding and Clenching Jaws

Teeth grinding wears down the enamel, exposing the underneath the dentin.

In addition, bruxism, primarily due to high stress, frustrations, misaligned jaws, and poor sleep, causes damage to the enamel, causing teeth pain

6. Teeth Bleaching Products

Chemical-based products like teeth whitening gels, strips, etc., can put you at a high risk of tooth sensitivity.

Most teeth whitening agents contain bleach and hydrogen peroxide, which have to penetrate the tooth and reach the dentin inside for effective whitening results.

Constant teeth whitening, in turn, weakens the enamel causing your teeth to be hyper-sensitive.

The good news is that teeth pain from using whitening products subsidies once you stop using the chemicals. It would be best to seek professional oral health care if you consider teeth whitening.

7. Sinus Infection

Sinus can cause compression of nerve endings near your teeth and jaws. This can cause hypersensitivity in teeth.

The above are the prevalent causes of why are my teeth sensitive all of a sudden.

Fortunately, it’s possible to prevent and treat tooth sensitivity.

Changing lifestyle habits and oral hygiene will go a long way in eliminating tooth pain. Here is more to prevent teeth sensitivity.
