Dental Attrition

Do you grind your teeth ?

Dental attrition is a type of tooth wear caused by tooth-to-tooth contact, resulting in loss of tooth structure, usually starting at the incisal or occlusal surfaces. Tooth wear usually increases with age.

Dental Attrition is the progressive loss of tooth structure caused by mastication or grinding between opposing teeth. The extent of attrition will depend upon the use to which an individual puts their teeth. People will often grind their teeth more when stressed at work or very busy in life in general. A lot of people will grind their teeth at night, unknown to themselves.
In severe cases of attrition, the protective layer of enamel, can become worn to the point that dentine is exposed, leading to tooth decay and increased dental sensitivity.
Dental attrition can also be linked with TMJ discorders.

Often patients will be unaware they grind their teeth and just notice that their teeth are becoming flatter and uneven. At this stage, patients will usually complain that their teeth look “worn, short and uneven in length”.

Signs and Symptoms

  • Loss of tooth structure including a flattening or thinning of the teeth
  • Damage or failure of prior dental restorations
  • Increased dental pain/sensitivity due to loss of the enamel
  • Sore or irriatated gums
  • Tooth discoloration as a result of loss of enamel and exposure of the dentine layer
  • Shortened or uneven anterior teeth

Sometimes, patients will be unaware they grind their teeth until the dentist identifies the signs.


There are many treatment options to help prevent against dental attrition including :

Occlusal splint (night guard) to wear at night to protect the teeth.

Composite (filling material) build ups for aesthetics and function.

Crowns are sometimes required to protect the worn teeth against further wear.

Orthodontic treatment to align their bite.

Treatment of dental attrition can vary depending on signs and symptoms so we advise to discuss with the dentists at Blackrock Clinic Dentistry.

Sensitive teeth

Do you suffer from sensitive teeth?

Do you brush your teeth and feel a twinge? Do you avoid eating/drinking anything cold due to the pain in your teeth?

Sensitivity of your teeth can range from a mild awareness of a tooth to a severe nerve type pain that radiates from your upper teeth to your lower teeth. Sensitivity can be described as a nerve type pain that can range in time from a few seconds after the stimulus is provided to hours.

If you are noticing sensitivity of your teeth then this is likely to be a warning sign of a dental problem.

What causes sensitive teeth?

  • Tooth decay
  • Fractured or lost fillings
  • Exposed dentine/root surface
  • Gum disease
  • Wear on teeth from grinding, erosion, clenching
  • Toothbrush abrasion

Today, we will discuss exposed dentine/root surface from toothbrush abrasion. We will give a summary of the other causes and refer you to our other more detailed blogs in relation to the other forms of wear.

A common cause of sensitivity is wear of enamel causing dentine/root exposure.  Toothbrush abrasion- is caused by brushing too hard and likely using a hard bristle toothbrush. The majority of people tend to brush too aggressively. These can lead to the enamel being worn away, particularly where the teeth meet the gums. The exposed dentine may become sensitive as it is no longer protected.


To prevent toothbrush abrasion, brush with a soft bristled brush in small circular movements or use an electric brush. Blackrock Clinic Dentistry love using a soft manual curaprox toothbrush .

Try to change which side you begin brushing as remember the side you brush first tends to be the side you brush best.

Dental decay: It is important to have a dental examination every 6 months to help prevent and treat tooth decay. If you have noticed a roughness in your fillings or any signs of wear on your fillings then it is important to have your teeth examined.

Dental Erosion: please see our blog below on dental erosion. This is the wear of dental enamel through an attack of acid from acidic foods, drinks, relux, etc.. This can lead to sensitivity as the dentine is no longer protected.

Grinding your teeth can lead to wear of enamel causing dentine exposure. Please discuss with your dentist if you feel you grind your teeth. We will give a more detailed discussion on grinding and clenching in our next blog.

Gum recession: receding gums occur naturally over time. This will lead to root exposure. This root exposure will then lead to root sensitivity.

Treatment of sensitive teeth

Use a desensitising toothpaste. This works by creating an artificial layer over the exposed root reducing sensitivity. You will need to use this toothpaste for at least a week before you may notice a difference. As suggested above, review how you brush your teeth with your dentist.

You may also require bondings (small fillings) over the exposed root which will make the root look more aesthetic also.

7 habits that destroy your teeth

Top tips on what to do and what not to do for a healthy smile- a summary of the article found below

1)Do not eat sugar throughout the day…if you are have a bag of sweets, eat them all at once so your teeth are not exposed to a constant stream of sugar…We do suggest avoiding the sweet foods and fizzy drinks altogether!

2)Avoid hard toothbrushes: Please use a soft brush and do not brush too hard as this will cause recession of the gums and lead to sensitivity of the teeth.. Concentrate when you are brushing and use a gentle technique

3) Drink water throughout the day to keep your saliva flowing.. saliva helps wash away plaque and contains agents that will help fight against decay

4)Eat cheese after your meal to help generate saliva and it also helps neutralise any acidic foods you may have eaten

5)Do not rinse directly after washing your teeth as toothpaste contains high levels of fluoride that helps fight against tooth decay. Use your mouthwash at lunch or when you come home in the evening

6)Flossing is very important for our teeth. Decay very often begins in between our teeth as our toothbrush alone will not clean effectively

7)Brush your tongue
