The following dental health symptoms may indicate wisdom teeth coming in: swelling of the gums, bleeding or tender gums, jaw pain, difficulty opening your mouth, an unpleasant taste in your mouth, or a foul odor in your mouth.   Any tenderness or discomfort around the back of your mouth is one of the first signs of wisdom teeth coming in. One or both sides can be affected. It would be accurate to describe this sensation as adult teething. The gums may also be swollen.   Headaches may be triggered. A trapped wisdom tooth can cause pressure to build up under the gums, which can trigger headaches. When you already suffer from frequent headaches, it can be difficult to detect this sign. Make sure you continue to visit a skilled dentist for regular checkups so they can monitor your oral health.   Infection can occur in the gums. Wisdom teeth roots may be awkwardly positioned as they erupt, resulting in only part of the tooth erupting. As a result, the gum tissue becomes very susceptible to active infections. Food can easily get lodged even with a minuscule opening, making it difficult to remove, even with thorough brushing and flossing. When not detected and treated immediately, this can escalate into a potentially serious infection known as pericoronitis. Whenever your wisdom teeth are coming in, this is the most serious sign to watch out for, so consult your dentist as soon as possible.
