What is the direct answer?
What does this question mean?
Plaque can inflame the gingiva, while food impaction, an appliance, an erupting wisdom tooth, or infection may cause local swelling.
What can you do next?
Brush gently, clean between teeth, and rinse with lukewarm salt water. Do not cut or squeeze the swelling.
When should you seek dental care?
Book care if puffiness lasts, recurs, bleeds, or is limited to one painful area. Fever or facial swelling is urgent.
What should you ask the dentist?
Ask whether this is gingivitis, a periodontal pocket, food impaction, trauma, or infection, and whether probing or an X-ray is needed.
Frequently asked questions
Can this have more than one cause?
Yes. Appearance, location, duration, and examination findings help distinguish irritation, infection, trauma, and tooth-related causes.
What should I avoid meanwhile?
Avoid picking, squeezing, harsh products, and any activity that repeatedly irritates the area while arranging care.
