Thanks for sharing your concern.
donot worry,i will suggest you for some home remedies
which if followed properly will solve most of your teeth problems.
if your tooth is decayed or you have holes in it. you have to,start brushing your teeth regularly .so that further decay can be prevented.
if you have gum problem,start using chlorhexidine
mouth wash periodically.this will reduce your gum infections. you can also do gum massage
with gum paint.
you can do frequent warm saline rinses,after food to prevent any food debris from getting accumulated and causing pain and infection.
also do flossing for your inter dental areas.
meanwhile keep looking for a charitable treatment camp where dental treatment is carried out free of coast or on very nominal fees.then you can visit there and get the required treatment done.
hope it is helpful to you.
