Hi..
Welcome to HEALTHCARE MAGIC..
All the symptoms that you are experiencing of sore mouth, tongue and
bleeding gums with cracks on tongue and now
numbness of mouth and lips can be due to causes like infection inside mouth,
allergic reaction,
acid reflux while can also be related to deeply decayed tooth causing inflammation numbness..
I would suggest you to consult an Oral Physician and get evaluated and a thorough clinical evaluation and investigation like x ray and
blood test can help in diagnosis and treatment can be done ..
As of now to reduce soreness take anti-inflammatory painkillers like ..
Do numbing mouthwash gargle containing Lignocaine..
Suck ice pops..
Avoid hot and spicy food..
Take a Vitamin B complex daily...
Do cool compresses over the swelling..
Hope this helps..
Regards .
