Hey! My dad had dentures for nearly 2 years and now he want to remove them and get all on 4 dental implants. Because of his smoking habit, his dentures are almost ruined and I don’t think even dental implants could help him if he doesn’t quit smoking. I have scheduled an appointment with Dr. Hagi from Thornhill Smile Centre in Toronto for next week. But before getting all on 4 dental implants I need him to quit his smoking habit. He too needs it but he is not able to control it. Can anyone here help me with some good tips? Also, I would like to know more about all on 4 dental implants. Thanks for your time!!
