Sensitive teeth

Sensitive teeth can cause pain whenever they’re used.

How it works:

Sensitive teeth occur when a tooth’s nerve becomes more sensitive and/or more exposed as its surrounding layers decrease in size.

Extra nerve sensitivity is also often caused by poor brushing technique which allows plaque to build up and agitate the immune system. cavities, gingivitis, periodontitis, trauma and recent fillings are other common causes.

Maxillary sinuitis can also cause the teeth in the upper jaw to become more sensitive – as can pains in the head and neck.

The body’s defence mechanisms:

Teeth react to sensitivity by increasing dentine production, which then fills the cavity containing the nerve.

Excess minerals in saliva – which normally protect against cavities and erosion – also help to reduce sensitivity by using calcium phosphate to block the small ‘tubes’ in dentine which cause sensitivity to be felt.

Risk factors:

Prevention:

Correct brushing technique combined with regular cleaning between the teeth will help to avoid cavities, gingivitis and periodontitis – all of which contribute to sensitive teeth.

You should also reduce your intake of acidic and sugar-rich foods, and if you suffer from frequent vomiting or acid reflux should see your doctor for an examination and treatment.

Your doctor should be contacted if you suffer from Maxillary Sinusitis.

What will your dentist/dental hygienist do?

To help with sensitive teeth, your dentist/dental hygienist must first establish why your teeth are overly sensitive. This is often due to multiple factors, so more than one treatment may be suggested.

The most common treatment will be advice on correct brushing technique, cleaning between your teeth and diet.

If you suffer from periodontitis, gingivitis or cavities, you will be treated appropriately – potentially with fluoride treatment or fillings.
