Which artery is responsible for supplying the mandibular teeth and tissues?

1. Buccal artery

2. Superior alveolar artery

3. Inferior alveolar artery

4. Lingual artery

The correct answer is: Inferior alveolar artery

The inferior alveolar artery is crucial for supplying blood to the mandibular teeth and associated tissues. Originating from the maxillary artery, it travels through the mandibular canal and branches off to provide oxygenated blood to the lower jaw's teeth, including the molars, premolars, and incisors. This artery also sends off smaller branches that supply the bone, periodontal ligaments, and gums in the mandibular region, thus playing a vital role in dental health and overall oral function. Understanding the role of the inferior alveolar artery is essential for dental professionals, particularly when considering procedures such as extractions or nerve blocks in the mandibular area, where adequate blood supply is critical for healing and recovery.
