Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems that soreness of tongue along with
tingling and
numbness and also formation of canker sores seems to be due to Apthous
Stomatitis leading to inflammation inside mouth and along with it there seems to be apthous ulcers or canker sores..
As she has used a new toothpaste it can b due to side effect of it..
I would suggest you to consult an Oral Physician and get evaluated and a thorough clinical evaluation and investigations like blood tests can help in diagnosis..
First of all stop using the toothpaste and use hypoallergic toothpastes..
Treatment of underlying cause will relieve the symptoms..
As of now you can start gargling with a numbing mouthwash containing Lignocaine to relieve the symptoms.
You can also take a
multivitamin tablet daily..
You can take anti inflammatory painkiller like
Ibuprofen..
Suck ice and do cool water rinses..
Avoid spicy food..
Hope this information helps..
Thanks and regards.
