Hi, so I jad braces before when I was around 14. And when I got them taken off I felt that my left canine tooth would sometimes hurt a little and would hirt a little more durong the winter time. Today it started hurting out of nowhere and felt that theres a lump next to my nose that wheneverI touch makes my canine tioth hurt hhorribly,  what can this be I am terrified because I do t want to get my tooth removed!
Hello, Thanks for writing to us. The pain associated with canine tooth after orthodontic treatment is due to dentin hypersensitivity. There is chance of wearing of enamel during orthodontic appliances are inserted. The lump may be arose due to abscess formed from periodontal infection. I would suggest you to get a thorough clinical evaluation by your dentist. Thorough scaling has to be done. Sensitive teeth have to be restored using tooth colored filling material. Use desensitizing toothpaste and interdental toothbrush to clean your teeth. Maintain good oral hygiene. The lump has to be curetted and Chat Doctor. Take care.
