Why Are My Teeth So Sensitive?

IS A SIMPLE SPOONFUL of ice cream enough to make you cringe because of the pain in your teeth? Do you have to be careful when you drink hot coffee that none of it touches your chompers? If you know the feeling, then you’re one of millions who experience tooth sensitivity. Let’s take a closer look at what causes tooth sensitivity and what can we do about it.
 

How We Feel Sensation In Our Teeth

Each of our teeth is covered in a layer of protective enamel. Underneath this is dentin, which is a lot like bone. Dentin contains thousands of microscopic tubules that run through it from the inside of the tooth out to the enamel. At the core of each tooth is the pulp chamber, which contains nerves and blood vessels. Because of those tubules, the nerves inside the tooth can detect what’s happening on the tooth’s surface.

Common Causes Of Tooth Sensitivity

If the enamel wears away, the tubules become exposed and the nerves in the dental pulp suddenly get much more stimulation than they like. This is what makes enamel erosion one of the main causes of tooth sensitivity. Without enamel, the nerves get a nasty shock whenever anything too hot or cold, or even too sweet or sour, touches the outside of the tooth.

Root exposure from gum recession also leads to sensitivity. The enamel only covers the crown of the tooth, not the roots. Those are protected by the gums. If the gums recede (sometimes as the result of teeth grinding or improper brushing over time), it exposes the roots.

Cavities and tooth injuries can cause sensitivity as well, even if you’ve been taking great care of your gums and enamel.

Use The Right Tools To Protect Your Teeth

Fortunately for all of us, there are ways to fight back, even if our teeth are already sensitive. Using a soft-bristled brush will help prevent further enamel erosion or gum recession. There is also special toothpaste formulated for sensitive teeth. Avoiding sugary and acidic foods and drinks (particularly soda) is another way to help your teeth.

We Can Help You Fight Tooth Sensitivity

Your best ally in the fight against tooth sensitivity is the dentist! Schedule a dental appointment as soon as you notice a change in your sensitivity level, or if you’ve been struggling with it for a while. The dentist can help protect your teeth with a fluoride varnish, perform restoration work to combat enamel erosion, and may recommend a gum graft for receding gums or prescribe a toothpaste to help with sensitivity.

Together, we’ll keep your smile happy and healthy!

A Closer Look At Our Teeth

WE USE OUR TEETH all day, every day, for chewing, talking, and flashing big smiles at friends and family, but what are the structures that allow our teeth to do so much? Let’s take a look at what our teeth are made of.
 

Layer 1: Tooth Enamel

The portion of each tooth that we can see above our gum tissue is the crown, and it has three different layers. On the outside is a protective layer of enamel, the hardest substance in our entire bodies. It has to be so that we can chew our food effectively. Unlike bone, enamel isn’t made of living cells, so it can’t repair itself as easily. It’s also vulnerable to acid erosion. We can protect it with regular brushing and flossing, dental visits, and by cutting down on acidic and sugary foods and drinks.

Layer 2: Dentin

Underneath that hard layer of enamel is dentin, which is softer and more yellowish. Like bone, dentin is calcified living tissue. Microscopic tubules run through it from the pulp to the enamel, which is how we are able to feel temperature in our teeth. If you’re experiencing tooth sensitivity, your enamel might have worn down enough to expose these tubules.

Layer 3: Dental Pulp

At the very core of each tooth is a chamber containing dental pulp, tissue consisting of nerves and blood vessels that keep the tooth alive and give sensation. This includes pain receptors that warn us when something is wrong with the tooth, such as tooth decay reaching the pulp.

Getting Down To The Roots

Like with icebergs, there’s more to teeth than we can see on the surface. The root extends deep into the jawbone, held in place by tiny periodontal ligaments and supported by gum tissue. The roots themselves are hollow. Nerves and blood vessels run through canals in the roots up to the pulp chamber in the crown.

Unlike the crown, the root of the tooth isn’t protected by enamel. Instead, it’s covered in a slightly softer substance called cementum. Cementum and healthy gum tissue work together to protect the root,but gum recession can leave it vulnerable.

Taking Care Of The Whole Tooth

We need all of these components for our teeth to stay strong and healthy, which is why we should keep oral health and hygiene as a high priority. Regular dental appointments and good brushing and flossing habits are essential for taking care of the outside of our teeth, and good nutrition helps keep them strong from the inside out!
