Best Treatments for Sensitive Teeth

Teeth sensitivity usually occurs when the underlying layer of the teeth i.e., dentin becomes exposed. This can happen due to erosion (wear and tear) and gum recession (when your gum tissue pulls away from your teeth, exposing the roots).

The roots of the teeth which are in the bone, contain thousands of tiny tubules that contain nerves (the pulp). These dentinal tubules allow stimuli i.e., hot, cold or sweet food to reach the nerve in your tooth, which results in the pain you feel.

Dental sensitivity can also be a symptom of other issues, including cavities, gum disease or a cracked tooth.

Depending on the severity, your dentist can offer solutions to get your teeth sensitivity under control.

Exposed Nerve Dentinal Tubules

What Causes Sudden Tooth Sensitivity?

Sensitive teeth are caused by damage or loss of enamel, which is the outer hard surface of your tooth.

This means the softer, inner layer of dentine is exposed in your mouth.

Dentine isn’t solid; it’s made up of tiny little tubules (a bit like these straws) that provide a direct path to the nerve of your tooth. These tubules contain fluid.

When something cold or hot touches the dentine, the fluid in the dentine tubules moves, this excites the nerve and gives you the sensation of pain. This movement of fluid is known as the hydrodynamic theory. The Hydrodynamic Theory was first shown in 1900 and further developed in 1966 by Swedish dentist Martin Brannstrom.

Many factors can lead to the development of sensitive teeth, including:

  • Brushing Too Hard: Over time, brushing too hard or using a hard-bristled toothbrush can wear down enamel and cause the dentin to be exposed. It can also cause gum recession (when your gum tissue pulls away from your teeth)
  • Gum Recession: Some people are genetically prone to thin gum tissue. Other people develop gum recession as a result of periodontal disease. With gum recession, your gum tissue pulls away from your teeth, exposing the roots.
  • Gum Disease: Inflamed and sore gum tissue may cause sensitivity because of the loss of supporting ligaments, which exposes the root surface that leads directly to the nerve of the tooth.
  • Cracked Teeth: Chipped or broken teeth may fill with bacteria from plaque and enter the pulp, causing inflammation.
  • Teeth Grinding: Grinding or clenching your teeth may wear down the enamel and expose underlying dentin.
  • Teeth Whitening Products: These products are sometimes contributors to teeth sensitivity. If you want to brighten your smile, talk to your dentist about teeth whitening which is done in a professional and in  monitored manner .
  • Age: Teeth sensitivity is highest between the ages of 25 and 30.
  • Plaque Buildup: The presence of plaque on the root surfaces can cause sensitivity.
  • Mouthwash Use: Some over-the-counter mouthwashes contain acids that can worsen teeth sensitivity if you have exposed dentin (the middle layer of the tooth). The acids further damage the dentin layer of the tooth. If you have dentin sensitivity, ask your dentist about the use of a neutral fluoride solution.
  • Acidic Foods: Regular consumption of foods with a high acid content, such as citrus fruits, tomatoes, pickles and tea, can cause enamel erosion.
  • Recent Dental Procedures: People can get sensitive teeth after fillings, teeth cleanings and dental filling placement. Sensitivity caused by dental procedures is temporary and usually disappears in four to six weeks.

If an over-the-counter desensitizing toothpaste or alcohol-free mouthwash isn’t decreasing your sensitivity, you may need an alternative medicated product which may work better for you. One of the most common treatments is desensitizing toothpaste, which contains compounds that help block the transmission of sensation from your teeth to your nerves. You will usually need a few applications before feeling any relief. The best dental clinics in Delhi offer best treatment options for your teeth sensitivity.

3. Wear A Mouthguard

When grinding becomes a problem, using a mouthguard at night can prevent damage to your teeth. Ask the dentist near you if this may be a viable solution for you.

4. Schedule A Dental Procedure

Depending on the source of your sensitivity, your dentist may recommend further treatment such as a cavity filling or fluoride application. In more severe cases, a root canal treatment may be recommended. The best dental clinics in Delhi are providing painless one sitting root canal treatments.

The best dentist in Delhi can take a small piece of gum tissue from somewhere else in your mouth and attach it where required. This will protect the exposed roots from damage and you will not feel sensitive as bad anymore!
