Symptoms of Root Canal problems – Our London dentist identifies the warning signs

Root canal treatment at Moorgate Smilepod in the heart of the city.

Our central London root canal expert Dr Daiva Pitkauskiene has identified some of the key warning signs of root canal infection.

Please note if you are experiencing any kind of dental pain it is important to see a dentist as soon as possible. At Smilepod we have five central London locations including, Canary Wharf, Moorgate, Soho, Bank (near Leadenhall Market) and Covent Garden. If you are experiencing any discomfort we will do our best to see you on the same day.

Symptoms of root canal infection

Brief discomfort or sensitivity when eating hot or cold foods

If discomfort is brief and only lasts a few moments it could mean there is an inflammation in the pulp of your tooth. Sensitivity can indicate a number of different problems such as decay, loose fillings or gum recession. If you are experiencing sensitivity, try using a toothpaste such as sensodyne for a few weeks. If symptoms persist make an appointment to see one of the friendly dentists at any of Smilepod’s central London studios

Sensitivity to temperature after dental work

Dental work can inflame the pulp causing temporary sensitivity. If you are experiencing sensitivity following dental treatment make sure you mention this in your review. After any dental work it is advised to see you dentist again for a ten minute review a few weeks later.

Pain when biting and chewing

This type of pain could be caused by a number of things such as decay, a loose filling or sometimes a crack in the tooth. However, it could also indicate damage to the pulp tissue inside the tooth. If you are experiencing this type of pain come and see a Smilepod dentist for a check-up. If the problem is pulp tissue damage, your dentist will discuss treatment options.

Persistent pain after eating hot or cold foods

This pain could indicate that the pulp in your tooth has been damaged either by deep decay or physical trauma. We recommend you see one of the Smilepod dentists as soon as possible so they can identify the cause of the pain. If necessary you will be recommended root canal treatment in order to save your tooth.

Severe toothache and pain, gum inflammation and pain when touched

This type of toothache could be caused by a bacterial infection which formed into an abscess. If you are experiencing severe pain come and see us and we will do whatever possible to relieve your discomfort.

Dull ache and pressure in upper teeth and jaw

A possible origin of this problem is a sinus headache. These are often felt in the face and teeth. Teeth grinding (or bruxism) is also known to cause this type of ache.

For relief from a sinus headache we recommend you see your GP. For bruxism, you should consult your dentist. If the pain is severe and chronic your dentist might refer you to an endodontist for evaluation.
