What Causes Sensitive Teeth?

If you sometimes find the taste of something hot or cold painful on your teeth, you may suffer from sensitive teeth.

Sensitive teeth is a common problem which may be caused by cavities and fractured teeth.

But it can also be caused by worn tooth enamel, a cracked tooth or an exposed tooth root.

Tooth enamel is the strongest substance in the body and it protects the crowns of healthy teeth. A layer called cementum protects the tooth root under the gum line.

The part underneath the enamel and the cementum is called dentin, which is less dense than enamel or cementum.

The dentin contains small hollow tubes or canals called tubules. When the dentin loses its protective covering, the tubules allow hot, cold, acidic or sticky foods to reach the nerves and cells inside the tooth.

This causes hypersensitivity and occasional discomfort but fortunately, the irritation does not cause permanent damage.

Following proper oral hygiene helps prevent the gums from receding and causing the pain of sensitive teeth.

Brushing your teeth incorrectly or even brushing too much can cause gum problems.

Your dentist will advise you on the best daily routine to maximize your oral hygiene.

Dental Emergencies: What to Do When You Can't Wait

Dental emergencies can happen unexpectedly and can cause a lot of discomfort and pain. Knowing what to do in a dental emergency can help you manage the situation until you can see your dentist. Here are some common dental emergencies and what to do:

1. Toothache:

Rinse your mouth with warm water and gently floss around the tooth to remove any food particles that may be causing the pain. If the pain persists, take over-the-counter pain medication and contact your dentist.

2. Broken or Chipped Tooth:

Save any pieces of the tooth if possible and rinse your mouth with warm water. Apply a cold compress to the area to reduce swelling and take over-the-counter pain medication. Contact your dentist as soon as possible.

3. Knocked-Out Tooth:

Hold the tooth by the crown and rinse it with water, but do not scrub it. If possible, place the tooth back in its socket and hold it in place with a clean cloth or gauze. If you cannot re-implant the tooth, put it in a container of milk or saliva and contact your dentist immediately.

4. Lost Filling or Crown:

Clean the affected tooth and apply dental cement or toothpaste to the area to temporarily hold the filling or crown in place. Contact your dentist as soon as possible to get it properly repaired.

5. Abscess:

An abscess is a bacterial infection that forms in the mouth and causes swelling and pain. Rinse your mouth with warm salt water and take over-the-counter pain medication. Contact your dentist as soon as possible to get it properly treated.

Dental emergencies can be scary and painful, but knowing what to do in these situations can help you manage the situation until you can see your dentist. If you experience a dental emergency, contact your dentist immediately or go to the nearest emergency room for immediate attention.
