Doxycycline (which belongs to a group of drugs known as tetracycline antibiotics) is used to treat periodontitis, but it is not a first-line drug for dental abscesses or anything involving the actual tooth because Doxycycline doesn't take up well in the tissues, though it takes up excellently in the extra-cellular fluid. It also can cause Gastrointestinal inflammation when used in therapeutic doses (which can be a contraindication for some people, such as people with chron's disease, colitis, Irritable bowel, etc.) , as well as the fact that Doxycycline becomes poisonous once it decays from sitting on the shelf too long.
The first line antibiotics used to treat most dental infections are most usually of the penicillin group (particularly Penicillin Potassium Clavunate, known as Penicillin VK or amoxicillin depending upon the severity of the infection ), unless they are specifically and absolutely contraindicated in a given patient. (e.g. drug allergies, etc.) This is because Penicillins have greater and much broader-spectrum reactivity to graham-negative bacteria than do the tetracycline drugs. Clindamycin is similarly used based on much the same reasoning. (Though we tend to be more judicious on using Clindamycin for the reason of avoiding the development of bacterial resistance because it is quite a bit more potent than most Penicillins.)
