Do you experience a sharp pain or discomfort when sipping a cold beverage or eating something hot and spicy? If so, you may have sensitive teeth. According to the Academy of General Dentistry, sensitive teeth affect about 40 million Americans.

The good news is that it’s treatable, but let’s dive into the truth about sensitive teeth and what causes them.

What are Sensitive Teeth?

Teeth are made up of three layers: enamel, dentin, and pulp. Enamel is the hard, outer layer of the tooth that protects the more sensitive layers underneath. Dentin lies beneath the enamel and contains tiny tubes that lead to the nerves in pulp.

Sensitive teeth occur when the enamel is worn down, and the dentin becomes exposed.

What Causes Sensitive Teeth?

There are numerous causes of sensitive teeth, including:.

Tooth decay or cavities
Gum recession
Worn enamel from brushing too hard
Cracked teeth
Exposed roots due to gum disease
Acidic foods and drinks that erode enamel
Teeth grinding or clenching
Whitening treatments
Orthodontic treatments that move teeth

How to Prevent Sensitive Teeth?

The best way to prevent sensitive teeth is by practicing good oral hygiene habits, including:.

Brushing twice a day with a soft-bristled toothbrush
Flossing daily to remove plaque between teeth
Avoiding sugary and acidic foods and drinks
Wearing a mouthguard at night if you grind or clench your teeth
Maintaining regular dental check-ups every six months

How to Treat Sensitive Teeth?

If you already have sensitive teeth, there are several treatments available that can help, including:.

Desensitizing toothpaste: This type of toothpaste contains compounds that block sensations from exposed dentin.
Fluoride treatments: Fluoride strengthens enamel and reduces sensitivity.
Dental bonding: Your dentist can apply a resin that covers exposed root surfaces.
Gum grafting: Your dentist can take tissue from another area of your mouth and attach it to exposed roots.
Root canal: If the tooth’s nerve is exposed or damaged, a root canal may be necessary to remove the nerve and restore the tooth.

Conclusion

Sensitive teeth can be an uncomfortable and even painful issue for many people, but it is treatable. Good oral hygiene habits and regular dental check-ups can prevent sensitive teeth, and several treatments are available to relieve symptoms.

Talk to your dentist if you’re experiencing sensitivity, so they can properly diagnose the problem and recommend a treatment plan.
