Are you experiencing sharp pain or discomfort when eating ice cream, drinking hot beverages, or brushing your teeth? You could be dealing with tooth sensitivity, a common condition that affects millions of people worldwide.
In this blog, we’ll explain what causes tooth sensitivity, how it’s treated, and what you can do to prevent it in the future.
What Is Tooth Sensitivity?
Tooth sensitivity (also known as dentin hypersensitivity) occurs when the underlying layer of your teeth, known as the dentin, becomes exposed. This happens when the protective layer of enamel or the gum tissue around your teeth wears down. When dentin is exposed, the nerves inside the tooth become more sensitive to stimuli like hot, cold, sweet, or acidic foods and drinks, causing discomfort or pain.
Common Causes of Tooth Sensitivity
There are several factors that can contribute to tooth sensitivity:
1. Worn Enamel
Enamel is the hard, protective outer layer of your teeth. Over time, it can wear down due to:
Brushing too hard with a hard-bristled toothbrush
Acidic foods and drinks (like citrus fruits, soda, and wine)
Teeth grinding (bruxism), which can wear down enamel
2. Gum Recession
When the gums pull back from the teeth, the sensitive roots are exposed. This can happen due to:
Gum disease (gingivitis and periodontitis)
Brushing too aggressively or using a hard-bristled toothbrush
Aging, as gums naturally recede with time
3. Tooth Decay or Cavities
Cavities can cause tooth sensitivity because they break through the enamel and expose the softer parts of the tooth. If you’re feeling pain when biting or chewing, you may have a cavity that needs treatment.
4. Recent Dental Procedures
If you've recently had dental work, such as a filling or teeth cleaning, you may experience some temporary sensitivity. This is common but should subside after a few days.
5. Cracked Teeth or Fillings
A cracked tooth or filling exposes the dentin and nerves, leading to pain when the tooth is stimulated.
6. Acidic Foods and Drinks
Frequent consumption of acidic foods and beverages like citrus fruits, coffee, wine, or soda can erode tooth enamel, leading to sensitivity.
How to Treat Tooth Sensitivity
1. Use Desensitizing Toothpaste
Specialized desensitizing toothpaste contains compounds that help block the transmission of pain signals from the surface of the tooth to the nerve. Regular use can help alleviate sensitivity over time.
2. Switch to a Softer Toothbrush
Use a soft-bristled toothbrush to prevent further damage to your gums and enamel. Brush gently to avoid wearing down the enamel and receding your gums.
3. Fluoride Treatments
Fluoride can help strengthen enamel and reduce pain. Your dentist may apply a fluoride gel or varnish to the affected areas of your teeth to improve protection and reduce sensitivity.
4. Dental Sealants
If you have sensitive teeth due to enamel erosion, your dentist may apply a dental sealant to the affected areas to protect the tooth surface from stimuli.
5. Dental Bonding or Crowns
If the sensitivity is caused by a crack or large cavity, your dentist might suggest dental bonding or placing a crown to cover the affected tooth and protect it from pain.
6. Root Canal Treatment
In severe cases, a root canal may be necessary if the sensitivity is caused by infection or inflammation of the pulp (nerve) inside the tooth.
How to Prevent Tooth Sensitivity
1. Brush Properly
Use a soft-bristled toothbrush and brush gently in small circles. Avoid aggressive scrubbing, which can wear down enamel and irritate your gums.
2. Limit Acidic Foods and Drinks
While it’s okay to indulge in acidic foods and beverages occasionally, try to limit their consumption. Rinse your mouth with water after consuming them to reduce their effects on your teeth.
3. Use a Mouthguard
If you grind your teeth at night, a custom night guard can protect your teeth from further damage and sensitivity.
4. Maintain Good Oral Hygiene
Brush twice a day, floss daily, and visit your dentist regularly for check-ups and cleanings. Keeping your teeth and gums healthy helps prevent conditions that contribute to sensitivity, like gum disease or cavities.
5. Stay Hydrated
Dry mouth can contribute to tooth sensitivity. Drink plenty of water to keep your mouth hydrated and promote saliva production, which helps protect enamel.
When to See a Dentist for Tooth Sensitivity
While tooth sensitivity is common, it can also be a sign of underlying dental problems. If you experience:
Severe or constant pain
Pain when chewing or touching a specific tooth
Bleeding or swollen gums
Tooth decay or cavities
It’s important to schedule an appointment with your dentist to get an accurate diagnosis and appropriate treatment.
