so for the past 2 months I’ve been getting tooth ache coming out of my K9 tooth what ever its called when ever i drink something cold and it hurts quite bad but it kinda goes away after brushing my teeth so one day i was relaxing drinking a cold bottle of water then my tooth starting aching after every sip so i thought why not swash the water round in my mouth all of a sudden the tooth that I’ve been feeling the pain out of makes a click noise and stops hurting completely like i could drink cold water with no pain then an hour passes and it start hurting again when drinking cold thing so i did the same thing as i did before and swash water around my mouth and i hear a click noise and the pain when i drink cold thing goes away again and came back an hour later again what should i do.
I am no dentist, but it sounds like you may have a cavity or hairline crack in your tooth . It is allowing the heat or cold to reach the nerve of the tooth, resulting in your pain and discomfort. The tooth is expanding or contracting ever so slightly depending on the temperature of the liquid in your mouth. You need to see a dentist.
