10 Reasons You Have Sensitive Teeth And How To Treat Them

If you’ve ever felt pain or discomfort after a bite of ice cream or a spoonful of hot soup you’re not alone. While pain caused by hot or cold foods could be a sign of a cavity, it could also be that you have sensitive teeth.

Tooth sensitivity, or “dentin hypersensitivity,” is exactly what it sounds like: pain or discomfort in the teeth as a response to certain stimuli, such as hot or cold temperatures.

It may be temporary or a chronic problem, and it can affect one tooth, several teeth, or all the teeth in a single individual. It can have a number of different causes, but most cases of sensitive teeth are easily treated with a change in your oral hygiene regimen.

Symptoms of sensitive teeth

People with sensitive teeth may experience pain or discomfort as a response to certain triggers. You may feel this pain at the roots of the affected teeth. The most common triggers include:

1. You brush with too much gusto. Sometimes tooth sensitivity comes from brushing with too much force or using a hard-bristled toothbrush. Over time, you can wear down the protective layers of your teeth and expose microscopic hollow tubes or canals that lead to your dental nerves. When these tubes are exposed to extreme temperatures or acidic or sticky foods, tooth sensitivity and discomfort can result. The simplest solution is to switch to a toothbrush with softer bristles and to be gentler when brushing.

2. You eat acidic foods. If the pathways to your nerves are exposed, acidic foods such as tomato sauce, lemon, grapefruit, kiwi, and pickles can cause pain. But avoiding these foods can help you avoid any tooth discomfort.

3. You’re a tooth-grinder. Even though tooth enamel is the strongest substance in your body, grinding your teeth can wear down the enamel. By doing so, you expose the dentin, or the middle layer of the tooth, which contains the hollow tubes that lead to your nerves. Talk to your dentist about finding a mouth guard that can stop you from grinding. The best guards are custom-made to fit your bite.

4. You use tooth-whitening toothpaste. Many manufacturers add tooth-whitening chemicals to their toothpaste formulas, and some people are more sensitive to them than others. If your toothpaste contains whitening agents, consider switching to one that doesn’t.

5. You’re a mouthwash junkie. Like whitening toothpaste, some over-the-counter mouthwashes and rinses contain alcohol and other chemicals that can make your teeth more sensitive — especially if your dentin’s exposed. Instead, try neutral fluoride rinses or simply skip the rinse and be more diligent about flossing and brushing.

6. You’ve got gum disease. Receding gums, which are increasingly common with age (especially if you haven't kept up with your dental health), can cause tooth sensitivity. If gum disease or gingivitis is the problem, your dentist will come up with a plan to treat the underlying disease, and may also suggest a procedure to seal your teeth.

7. You have excessive plaque. The purpose of flossing and brushing is to remove plaque that forms after you eat. An excessive buildup of plaque can cause tooth enamel to wear away. Again, your teeth can become more sensitive as they lose protection provided by the enamel. The solution is to practice good daily dental care and visit your dentist for cleanings every six months — or more frequently if necessary.

8. You’ve had a dental procedure. It’s common to experience some sensitivity after a root canal, an extraction, or the placement of a crown. If symptoms don’t disappear after a short time, you should schedule another visit to your dentist, as it could be a sign of infection.

9. Your tooth is cracked. A chipped or cracked tooth can cause pain that goes beyond tooth sensitivity. Your dentist will need to evaluate your tooth and decide the right course of treatment, such as a cap or an extraction.

10. There is decay around the edges of fillings. As you get older, fillings can weaken and fracture or leak around the edges. It’s easy for bacteria to accumulate in these tiny crevices, which causes acid buildup and enamel breakdown. Be sure to see your dentist if you notice this type of tooth sensitivity between visits; in most cases, fillings can be easily replaced.

How to treat sensitive teeth

So if you’re looking for sensitive teeth treatment there are multiple options, and most dentists have their own favorites which they’ll most likely recommend to you for your specific case. There is no “single solution” that will work the same for every case. It’s essential for the well-being of your teeth that you get the proper diagnosis from your dentist so you can treat your tooth sensitivity properly. When approached properly, you’ll have greater success in decreasing or even eliminating tooth pain that comes from tooth sensitivity.

  • Desensitizing toothpaste. After several applications, desensitizing toothpaste can sometimes help block pain associated with sensitive teeth. There are a variety of products available over-the-counter. Ask your dentist which product might work best for you.
  • Fluoride. Your dentist might apply fluoride to the sensitive areas of your teeth to strengthen tooth enamel and reduce pain. He or she might also suggest the use of prescription fluoride at home, applied via a custom tray.
  • Desensitizing or bonding. Occasionally, exposed root surfaces can be treated by applying bonding resin to the sensitive root surfaces. A local anesthetic might be needed.
  • Surgical gum graft. If your tooth root has lost gum tissue, a small amount of gum tissue can be taken from elsewhere in your mouth and attached to the affected site. This can protect exposed roots and reduce sensitivity.
  • Root canal. If your sensitive teeth cause severe pain and other treatments aren't effective, your dentist might recommend a root canal — a procedure used to treat problems in the tooth's soft core (dental pulp). While this might seem like a significant treatment, it's considered the most successful technique for eliminating tooth sensitivity.
