Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems that the white scar like tissue that is present over the gumsvandvinner lip where you used to dip tobacco can be due to causes like
Frictional Keratosis that is a harmless overproduction of keratin layer over the mucosa asca protective phenomena to prevent damage to mucosa with bthe friction and chemicals..
Other cause can he
Leukoplakia tyatbos also over production of Keratin but there is also disturbance in cells known as cell
dysplasia..
It is a Precancerous lesion and needs mime medical assistance..
I would suggest you to consult an Oral Physician and get evaluated and a clinical evaluation and investigations like
Biopsy can be done for diagnosis..
In case if it is due to Frictional Keratosis it will get resolved on its own once the tobacco intake is stopped..
In case of Leukoplakia you can be advised Multivitamins and anti oxidants like
Lycopene for atleast 2 to 3 months..
It also gets resolved if tobacco intake is completely stopped..
Hope this information helps..
Thanks and regards.
