Wisdom teeth don’t need to be removed if they don’t cause pain, swelling or discomfort. But if they emerge partially or are stuck in the gums, they can become susceptible to infection as food particles get trapped in them. Bacteria can also form on roots of other molars, leading to tooth decay and cavities. Another complication is the development of cysts and tumours in the gum. Wisdom teeth extraction is advised to prevent any potential complications in the future. Dentist North York clinic is now accepting new patients – if you have concerns about your wisdom teeth, get qualified advice as soon as you can.
