First you have not told your age. second you are not a seizure
patient. Third you have not mentioned how many times you had seizure and extend of damage on the teeth.
Without knowing all these information it is very difficult to give opinion. my suggestions may be helpful to you.
Permanent dentures with or without existing teeth are available. If extraction and permanent dentures are indicated govt. hospital is better as you are in financial constrain.
If you are a regular seizure patient consult your Neuro Physician before fixing dentures.
