I'm afraid of teeth falling out during tartar removal (scaling). does this make sense?

Tartar on teth: No need to worry if you have a competent dental hygenist.

Deep Cleaning: A deep cleaning is needed when you have perio disease. If you have a large amount of plaque buildup you may notice that your teeth become loose after this procedure, but the only way to try to make them healthier again is to do the deep cleaning. Leaving the buildup there will only cause you more damage.

Not likely: If you have very advanced periodontal disease and the teeth are really very loose, you should not be having a typical scaling and should be seeing a periodontist. If you have minor mobility in your teeth, it is not at all likely that your teeth can come out during a scaling and they may actually tighten up after tereatment when the bacteria is removed causing your bone loss and teeth to be loose.

Get it done: Removing tarter will not cause teeth to chip. Removing tarter will not cause teeth to fall out. Leaving tarter in place will only result in more bone and tissue loss around the teeth...Get rid of it.
