Hello  sir.. Wisdom teeth is one that fails to erupt in its position in the given period of time .. Consequencs of  wiadom teeth **Pericoronitis

Hello Wisdom tooth errupts between 18-23 years. So it's quite normal. It might not be pain.... Just the pressure that you are experiencing. It takes months to errupt out and you might have this on and off irritation until then. If the pain or pressure goes intolerable.... You can get it removed. Usually wisdom tooth creates problem because there often isn't enough place for it to errupt.

Hello sir, permanent solution for your condition is removal of your wisdom. You may take pain medication for temporary relief. You may also use a mouthwash or salt water gargle on the affected side 3-4 times a day.

Hello sir, A permanent solution to your problem is to extract the wisdom tooth as they are non- functional and do not play any role in mastication. For bad smell, you should visit your dentist and get scaling and polishing done followed by rinses with chlorhexidine mouth wash.

Hello sir, if your wisdom tooth is creating pain and discomfort, it's better to extract it, because it's an extra, non-functional tooth, which may create ulcer in your mucosa due to constant irritation... So, it's safe that you extract it... For bad smell, after extraction, do a general cleaning and polishing followed by chlorhexidine mouthwash and brush twice daily...
