Posted on: 24 September 2020

A toothache is an irritating and painful symptom indicating that something is going on with your dental health. At one point or another, most people experience toothaches. The top way to prevent it is to maintain good oral health and schedule regular visits to the dentist for examination and treatment of any emerging issues. If your tooth starts to ache, the best move is to inform a dentist for treatment. Even if the pain stops, ensure you make that appointment to ensure that the problem is identified and the dentist provides the necessary treatment. Is your tooth persistently aching?

Cavities are among the most common causes of toothaches. A cavity is a hole in your tooth caused by bacteria, which produces an acid that causes damage to the enamel. This allows the bacteria to penetrate your tooth and cause an infection. To prevent cavities, stay away from sugary drinks, foods, and snacks. Also, maintain good oral hygiene and make regular visits to the dentist to ensure that if you do develop any cavities, your dentist provides treatment early enough. 


If you leave a cavity untreated, one of the most common consequences is an accumulation of pus inside your teeth or gums. The amount of pain you experience will depend on the depth at which the abscess has formed. If the damage is not too severe, the dentist can treat it with an incision and draining the pus, or by carrying out a root canal. However, if the damage is too severe, you may require a tooth extraction. 

Tooth Sensitivity

If the tooth's enamel has been eroded, you may sometimes experience tooth sensitivity to cold or hot drinks. This is because the tooth's nerve endings are exposed, and this can cause pain. One of the best ways to relieve this pain is by using desensitising toothpaste, which helps to soothe the pain. Other causes of tooth sensitivity include bruxism, which can also cause headaches and toothaches. 


This occurs when the pulp of the tooth becomes inflamed. The pulp refers to the soft tissue found at the centre of your tooth. Usually, it's a result of untreated cavities, trauma, or multiple tooth restorations. If treated early, the dentist will recommend a filling to cover the cavity. If left untreated, your dentist may eventually have to do a root canal or a tooth extraction. 

Gum Disease

If you experience pain when you're chewing and your gums have changed to a reddish or bluish colour, chances are high that you're suffering from gum disease. You may also experience irritated or swollen gums. The pain when chewing should be reported to a dentist immediately, before it worsens to a condition called periodontal disease.

If your tooth is aching, ensure you make an appointment with an experienced and licensed dentist. Leaving it untreated could lead to a worse situation.
