The Inside Scoop On Tooth Sensitivity!

Do you experience pain or discomfort when eating something hot or cold? If so, you may be experiencing what is known as tooth sensitivity or "dentine hypersensitivity".

There are many different reasons why this happens. It can happen to several teeth, all teeth or one tooth. 

Although it can be reversed, there are also times when it's irreversible. Tooth sensitivity can range from mild to intense and can come and go at any given time.

Having tooth sensitivity could signify that you have a cavity. Some people have naturally sensitive teeth due to having a thinner layer of enamel.

Most cases of sensitive teeth are related to your oral hygiene, which is why it's essential to have a dental check-up every year and get a clean every six months.

This article looks at the best way to prevent and help tooth sensitivity.

Before & After (Click To Enlarge)

Tooth sensitivity is a pain or discomfort that occurs when eating hot or cold food and drinks. It can occur due to worn tooth enamel, exposed roots and cavities. This can sometimes affect the enjoyment of food.

The strength of your enamel primarily influences tooth sensitivity. Enamel is a thin outer covering of the tooth, and this tough shell is the hardest tissue in the human body. 

Tooth enamel acts as a shield for the more sensitive inner tooth layer called the dentine. When you eat and drink foods that are high in acid, this can wear away your enamel and expose the dentine causing tooth sensitivity.

What Causes Tooth Sensitivity? ​​

Some people have naturally sensitive teeth due to having thinner enamel. Over the years, we eat and drink acidic foods that wear down our enamel. Dr. Peter Doherty

The best way to help prevent tooth sensitivity include:

  1. Getting regular checkups with your dentist 
  2. Getting a dental scale and polish with a hygienist every six months
  3. Use an oral b electric toothbrush or a soft-bristle toothbrush
  4. Brushing your teeth twice a day and flossing
  5. Using teeth whitening products sparsely
  6. Wearing a mouthguard if you grind your teeth

Do I Need To Go And See My Dentist?

Yes, it's important to see your dentist regularly. As mentioned before, tooth sensitivity can range from mild to chronic.

Visiting your dentist early can make the difference in getting a minor, less intrusive treatment rather than a long, costly investment. So always visit your dentist no matter how small the issue is.

How Is Tooth Sensitivity Treated?

We can treat tooth sensitivity in a number of ways. If your tooth sensitivity is mild, you can try products from your local pharmacy. It would also help if you bought a fluoride toothpaste that is clearly labelled for sensitive teeth as it will have desensitising ingredients that help stop the discomfort.

Always ensure that you don't rinse off the toothpaste. You should always treat toothpaste like medicine, not like soap. Dr. Paul O'Connell

Using softer toothbrushes and brushing more gently can also help. If home treatments don't work, you can talk to your dentist about prescription toothpaste and mouthwash.

They may also apply fluoride gel or a desensitising coating. These can help to strengthen the enamel and protect your teeth.

Take Care of Your Tooth Enamel

take care of your tooth enamel - teeth sensitivity - dr niall vallely - 3Dental

It is imperative to take care of your enamel as it helps protect you from tooth decay. Over the years, you will wear down the enamel barrier, but the best way to keep it strong is to:

  • Limit sugary foods and drinks
  • Avoid anything acidic 
  • Eat food that protects enamel (calcium)
  • Avoid over-brushing 
  • Use an electric toothbrush or a soft toothbrush
  • Ensure your toothpaste has fluoride in it
  • Get regular checkups with your dentist
  • Ensure your oral hygiene is good
  • Wear a nightguard if you grind

How Do I Know If My Tooth Nerve Is Exposed?

Your nerve will never be exposed to the naked eye.

Still, if your sensitivity is lingering moments after consuming anything hot or cold or even if cold air gets at the tooth, this could be an indicator that your nerve is inflamed and could need a filling or a root canal

If you are experiencing this kind of sensitivity, we recommend seeing your dentist for a checkup.

Can A Tooth Nerve Heal Itself?

If you have gotten a deep filling and are experiencing pain, it may be that the filling has reached a nerve and has irritated it. The nerve should heal itself, but you may require dental intervention if pain or sensitivity does not subside within two to four weeks.

Which Toothpaste Is Best For Sensitive Teeth?

There are many kinds of toothpaste that help with dental sensitivity. The thing to look out for is to ensure it's labelled for sensitive teeth and has fluoride. 

You can find many options in most supermarkets and pharmacies from brands such as KIN, Sensodyne, Oral B and Colgate.

In conclusion, tooth sensitivity is something that can happen to anyone. We all can get pain or discomfort at some point in our lives. It's important to have a good relationship with your dentist where you can ask them questions and come to them if you have any issues. 

We recommend getting a regular check-up at least once a year and a dental clean every six months. Following these guidelines will help your oral hygiene and limit the amount of treatment you might need in the future. 

Your teeth are with you for life, so be sure to take care of them!
