Pain in the gums along with the feeling that an extra tooth is growing is most commonly caused by the eruption of a wisdom tooth. Wisdom teeth usually appear in the late teenage years or early twenties and may cause pain, swelling, gum irritation, difficulty chewing, or a feeling of pressure in the mouth when there is not enough space for them to grow properly. Sometimes the tooth only comes out partially, allowing food and bacteria to collect around the gum, which can lead to infection and discomfort. In a few cases, the pain may also be due to a gum infection, tooth decay, or an extra tooth growing in an abnormal position. A dental check-up and an X-ray are often needed to identify the exact cause. Treatment depends on the reason behind the pain. If a wisdom tooth is causing inflammation or infection, the dentist may recommend pain-relief medicines, warm saltwater rinses, cleaning of the affected area, or antibiotics if there is swelling or infection. If the tooth is impacted, growing sideways, or causing repeated pain, removal of the tooth may be advised to prevent future problems. Until you visit a dentist, maintain good oral hygiene by brushing gently twice daily, rinsing your mouth after meals, and avoiding very hard, spicy, or sticky foods that can worsen irritation. You should seek prompt dental care if you develop severe swelling, fever, pus discharge, difficulty opening the mouth, or severe pain, as these symptoms may indicate a spreading infection that needs immediate treatment.
