Swelling in last teeth
Swelling around the back teeth can come from gum infection, an impacted wisdom tooth, decay, or an abscess.
The short answer
Swelling near the last molars often involves the gum over a partially erupted wisdom tooth, but decay, a periodontal pocket, or a dental abscess can also cause it.
What does swelling near the last teeth involve?
The clinical subject is the teeth, gums, jaw, or dental material named by the question. Its meaning depends on the anatomy involved, the timing of the change, and findings from an examination.
What can you do about swelling near the last teeth?
Record the location, onset, triggers, medicines, and relevant medical history, then follow the product or appliance instructions that apply. A dentist can use examination and targeted imaging to identify the cause.
When should swelling near the last teeth be checked?
Seek prompt care for severe pain, increasing swelling, fever, pus, uncontrolled bleeding, trauma, or difficulty breathing or swallowing. Persistent symptoms also warrant an examination.
What should you ask about swelling near the last molar?
Ask what structure is affected, which findings support the diagnosis, what treatment choices exist, and what changes should prompt urgent review.
Frequently asked questions
What is the first useful step?
Describe the symptom or goal clearly and arrange an examination when it persists or affects eating, sleep, or daily activity.
Can home care replace diagnosis?
Home care may reduce irritation, but it cannot identify decay, infection, fracture, gum disease, or a poorly fitting restoration.
