Re: Major tarter / plaque behind front bottom teeth
The back of the front bottom teeth is where the most plaque will build up. The tongue has alot to do with that. Try a tongue scraper if you have white on your tongue.
You need to get the plaque professionally removed again first. Please do this! If you don't, the bacteria it carries will just eat away at the bone and the teeth will fail and you'll be in a pickle!
Getting it removed will allow them to tighten back up. This will NOT happen unless you get that plaque out of there and you can't do it alone. You need a professional cleaning to reach it.
Once they are thoroughly cleaned, the very BEST way to keep plaque from forming there again is to FLOSS daily without fail. Floss is the only thing that will reach below the gumline and remove the plaque building up there.
I can't stress this enough!
Floss should be place down along the gumline to form a "C" around the toothbase as far below the gumline that is comfortable and then lifted up. This removes the plaque along the tooth base. It's VERY important that you add this to your regular two minute, twice daily brushings. If you can, add a water pik to your routine in the evening. Brush at least twice daily. Plaque hardens in a about 12 hours. Once it hardens it's very difficult to remove. That's why twice a day brushing is advised.
Floss should be your very best friend. If you want to limit the amount of plaque build up you need to get your teeth cleaned, and then brush twice a day and floss daily. It's the only way.
Hope this helps.
My best to you,
