Could i get a terrible sore throat and hoarse voice from a dental abscess?

Yes: If the dental abscess is draining into your mouth, such as would occur if there were a fistula, it is very possible that the chronic pus draining down your throat could give you quite a sore throat. Since the pus eminating from the abscess via the fistulous tract can carry a lot of bacteria with it, your throat could actually become infected beyond just becoming sore. Have the abcess treated...

It's possible: A dental abscess can drain to the tonsils causing sore throat or bacteria draining into your mouth from the abscess can infect the tonsils also causing inflammation and soreness of your throat. If you suspect that you are suffering from a dental abscess see your dentist to get treatment. There are other causes of sore throat and hoarseness but you need to rule out the dental cause.

Definitely: A dental abscess can sometimes quickly turn into a parapharyngeal space abscess, with soreness of the throat, difficulty swallowing and a potential airway problem. Dental abscesses need to be treated and resolved before more serious problems occur.
