What causes lump behind the tooth?
Patient: hi. just woundering...... im worried about my bottom teeth. for a few months my wisdom teeth have been trying to come through, im 25 , but there is no room. the pressure is horrible it comes and goes for a week or so every few months, but its done something to my front tooth, teeth. i hav overcrowed teeth anyway at bottom , one of my front tooth on bottom sits behind others always has but its moving more i think and now there is a bone like hard sensitive lump behind that tooth ? what is it. it has affected the way i bite and eat. is it my tooth pushing out from underneath. ??? please help is this costly ???? Doctor: Thanks for your query, I have gone through your query.The pain and swelling(lump)  could be because of the gum infection over the wisdom tooth (pericoronal infection leading to space infection).Consult a oral physician and get a radiograph done to rule the amount of space present for the tooth to erupt if space is there for the tooth to erupt then the gum covering over the wisdom tooth can be removed.If the space is not available then you have to get the wisdom tooth removed. Mean while you can take a course of antibiotics like amoxicillin and metronidazole (if you are not allergic). The wisdom tooth might damage to the next second molar. so get it treated as early as possible. There might be movement of the front teeth because of the pressure from the wisdom tooth.I hope my answer will help you, take care.
