There are four main categories of prohibited Melachah related to brushing teeth on Shabbos with a regular toothbrush and regular toothpaste. These issues vary for individual communities and contemporary poskim. Now, thanks to the new Shabbos Toothbrush and specially formulated Shabbos Toothwash, these Melachos are avoided, allowing you to brush your teeth on Shabbos according to most opinions:

Sechita: No sqeezing liquid with bristles.
Squeezing liquid out of a solid in which it was absorbed is prohibited on Shabbos. When wet, densely packed nylon bristles of a regular toothbrush are pressed against the teeth, many poskim consider it is as if the water is squeezed out of the bristles and forbid using a wet toothbrush. The rubber bristles of the Shabbos Toothbrush are far enough apart that it is obvious that liquid does not get absorbed into the bristles and is not squeezed out.
Chavalah: No bleeding gums.
Causing oneself to bleed on Shabbos is prohibited. Sharp nylon bristles of a regular toothbrush can cause gums to bleed. The soft rounded rubber bristles of the Shabbos Toothbrush do not cause bleeding. In the extremely rare case that very sensitive gums bleed even with the Shabbos Toothbrush, consult your local Rabbi and see your dentist!
Memareach: No spreading of paste with the Shabbos Toothwash.
Spreading a cream or ointment onto an object used as an applicator to the body is prohibited on Shabbos. Therefore, most poskim prohibit use of regular toothpaste or gel applied to any toothbrush. Shabbos Toothwash is a concentrated liquid and this prohibition does not apply. We do not recommend using the Shabbos Toothbrush with any product other than Kosher Innovations Shabbos Toothwash Also, the Shabbos Toothwash is certified kosher by the OU.
Uvdin D'Chol: No using a weekday toothbrush on Shabbos.
If a regular activity involves something that one may not do on Shabbos, that activity will be classified as a weekday activityy. For some poskim who permit the use of a regular toothbrush without toothpaste this prohibition would apply to using one's weekday toothbrush and they require a separate and even distinctive toothbrush for Shabbos. The Kosher Innovations Shabbos Toothbrush was designed specifically for Shabbos and not for weekday use, eliminating the issue of Uvdin D'Chol according to all poskim.
