Hi..
Can understand your concern..
As per your complain
excessive salivation is known as Ptyalism or Sialorrhoea and can occur due to a number of causes..
It can be due to any
nerve disorders involving nerves which are supplying the salivary glands, due to disorders of salivary glands, due to oral/mouth infections,dental infections,
acid reflux,medications like tranquillizers, anticonvulsants etc..
All or any of these can lead to
hypersalivation and bad odour in mouth and deposits on teeth can also occur due to hyper salivation..
I would suggest you to consult an oral pathologist and get evaluated and treatment can be planned according to the disease causing you the problem..
For foul smell and deposits on teeth get a professional cleaning of teeth done..
Use mouthwash especially flavoured ones for maintaining a fresh breath and smell..
Get treated for any dental infections as they can also cause hypersalivation
Getting the underlying cause treated can gradually reduce the problem..
Hope this information helps..
