What Makes My Teeth So Sensitive?

Posted in Root Canals

Dental hypersensitivity can have a number of causes. A combination of factors, in some cases. To figure out what’s going on with your teeth, it helps to get a little background info.

Anatomy Of A Sensitive Tooth

All teeth have hollow chambers in their centers. These spaces are filled with blood vessels and loads of nerves. The nerves pick up on temperatures via fluid-filled pores that fill the dentin (middle layer). These pores are insulated on the outside by the outer layer, the enamel. Enamel only covers the top portion of the tooth that’s visible when you smile. Tooth roots don’t have that protection.

How Teeth Get Sensitive

Those tiny nerves in teeth become more exposed to the outside world through two main ways:

  • Enamel is compromised
  • Roots are exposed

Enamel can be damaged or worn via acid erosion, fracture, decay, or simply years of use. Sensitive roots can be exposed as a result of orthodontic treatment, a bad bite, aggressive tooth brushing, or gum inflammation. Some other possible causes of sensitivity include getting a new filling, losing all or part of a restoration, and receiving a blow to your tooth.

What You Can Do About Sensitivity

You may be able to pinpoint a specific area of sensitivity. Or maybe not! It’s possible to suffer this complaint in a generalized way. Start out by taking your meals and drinks neither too hot nor too cold. Switch to a fluoride-rich desensitizing toothpaste to fortify your enamel.

Most importantly, see your dentist ASAP. Some sensitivity can indicate a serious nerve problem that requires root canal therapy. Whatever the case, you’ll get some practical advice and suggestions to help you get relief!

What You Can Do About Sensitive Teeth

Posted in Fillings

Why do some teeth get so sensitive? A few common contributing factors include:

  • Tooth decay
  • A small fracture
  • A teeth grinding or clenching habit
  • Gum recession
  • Poor oral hygiene
  • A new dental restoration

Your teeth are alive with their own complex – and very small – systems of nerves and blood vessels. Any time the outer enamel layer is compromised, your sensitive tooth is exposed to the oral environment.

3 Reasons Teeth Become Sensitive

First of all, the tough enamel layer can be disrupted by a fracture or dental restoration. Even strong dental fillings and crowns can cause some sensitivity for a little bit as your tooth gets used to them.

Second, besides being mechanically compromised, the enamel can also be worn down by acid in dental plaque left on the tooth.

Thirdly, when gums recede, they leave the more sensitive root layer of a tooth exposed to temperature changes.

Here’s What You Should Do

If your tooth starts hurting inexplicably, it’s a good idea to see your dentist for an exam. X-rays which can reveal whether something like decay is the hidden cause of sensitivity.

Reduce tooth sensitivity by keeping up with good oral hygiene. Brush and floss often and use fluoride-containing products to strengthen your enamel. A sensitivity toothpaste contains lots of minerals for reinforcing your teeth against damage.

Your dentist will make sure that your dental health is stable when you stop by at least twice a year for checkups. He or she will make recommendations for professional therapies that can reduce your discomfort.

Talk with your dentist about finding a treatment that’s best for addressing tooth sensitivity.

4 Causes of and Solutions for Sensitive Teeth

Having sensitive teeth is one of the most uncomfortable things to live with. It affects what you eat and even how easily you can breathe in through your mouth. Tooth sensitivity can seem like an ongoing and annoying battle.

Here are four common reasons teeth become sensitive and the best ways you can cope:

  1. Weather Changes

If you live in an area that experiences some extreme weather changes, then it may be difficult for your teeth to keep up with the change. It’s not unusual for certain teeth to become inexplicably more sensitive in frosty winter months.

What You Can Do: Try incorporating a sensitivity toothpaste into your routine. These pastes contain potassium nitrate which helps block open sensitive pores in tooth enamel.

  1. Acid (in Diet)

Acidic foods erode teeth’s protective enamel layer, making them much more sensitive.

What You Can Do: Limit the amount of acid in your diet. Rinse your mouth well before brushing. Chew a sugar-free gum to stimulate saliva flow, which neutralizes acids.

  1. Poor Oral Hygiene

Dental plaque is very acidic. A heavy build-up of plaque and tartar will cause gum inflammation and recession. When gums recede, more sensitivity-prone surfaces of the teeth are exposed.

What You Can Do: Schedule routine dental cleanings. Floss daily and brush with a soft toothbrush. Use a sensitivity toothpaste and work extra fluoride into your routine.

  1. Problem with the Tooth

A tooth may be sensitive because of decay, fracture, or nerve damage.

What You Can Do: Visit your dentist for an exam and x-rays to find out which treatment is right for you. Whatever the cause, your dentist will help you figure it out!

4 Ways to Treat Tooth Sensitivity

Sensitive teeth can be caused by a wide variety of factors. For this reason, there isn’t a magic cure-all that works in each case. But let’s start by considering a few of the most effective ways you can reduce sensitivity.

  1. Keep Your Teeth Clean

Plaque will make teeth more sensitive, so removing debris is important to keeping your enamel strong. Your brushing routine should include:

  • Using a soft-bristled brush which is gentler on tooth enamel
  • A sensitivity formulated toothpaste

Make your sensitivity toothpaste do double duty. After flossing, brushing, and rinsing, spread a dab of the toothpaste directly on sensitive spots right before bed.

  1. Cut Back on Teeth Whitening Products

Whitening products usually contain peroxide as the bleaching agent. This chemical reaches deep into the pores on teeth to lift stain. It also opens up the pores, exposing sensitive nerves in the tooth to the surrounding environment.

If you find that you’re unexpectedly dealing with sensitive teeth, look into the products you use that claim to whiten teeth. Give them a break for a week or two and see if your teeth start feeling any better.

  1. Avoid Acidic Foods

Highly acidic drinks and foods will irritate spots that are already weakened by cavities. These foods will also wear on the enamel of healthy teeth, causing irritation. Brush well after each meal and try to drink water more than sweetened drinks.

Still not sure what’s causing your sensitivity? Then now’s a perfect time to schedule a visit to your local dental office! Ask your dentist about what could be causing your sensitivity and what can be done about it.

3 Ways to Stop Tooth Sensitivity

Posted in Teeth Whitening

Generalized tooth sensitivity can be a burden that keeps you from enjoying the foods you like, or even from smiling when the weather is cold. While some types of tooth sensitivity are a signal that you have an infection or decay, generalized sensitivity is typically more of a burden that doesn’t affect the health of your smile. Here are 3 tips to adhere to, which can help stop your tooth sensitivity:

#1: Pay attention to what teeth whitening products you are using.

Everyday products that you use at home may be the main cause of your troubles. Even using whitening toothpastes can create significant sensitivity across your smile, and is one of the most common reasons for dental patients experiencing sensitivity. Instead, use a sensitivity toothpaste that will protect the delicate pores of your teeth and prevent extra nerve stimulation, or alternate it with your whitening toothpaste. If you’re using a teeth whitening gel, consider using a smaller concentration or reducing your wear time.

#2: Avoid acidic foods and drinks.

Lemons, diet soda, or sour foods can alter the pH in your mouth so that it becomes very acidic. This will erode layers of enamel across your teeth, causing the underlying portion to experience stimulation when it shouldn’t. Brushing too hard can do the same thing!

#3: Supplement with a fluoride rinse or gel.

Additional fluoride and mineral application to your teeth can help build up weak areas and diminish areas of sensitivity. Over the counter rinses are useful, not to mention they also protect your teeth from decay. Prescription strength gels can be accessed through your dentist, if your sensitivity is severe.
