Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your health concerns..
As per you query Hexigel is an antimicrobial ointment that contains Chlorohexidine Gluconate 1% w/w that is used in case of mouth ulcers to kill the local pathogens in mouth that act as irritants and by destroying them it helps in healing ulcers fast..
It should be applied gently over the ulcers and should not be rubbed or brushed as rubbing or brushing can cause
injury and further be damaging..
So it is better that you apply it gently over the ulcers 2 to 3 times a day..
You can also apply a numbing gel containing Lignocaine to reduce pain..
Along with if you suck ice pops, do salt water rinses and take a
multivitamin tablet for 15 days will be further relieving faster..
Avoid spicy and hard foods as it can further irritate the area..
Hope this information helps..
Thanks and regards..
