My wisdom tooth start to appear and I have pain in my left side of head and sometimes on teeth is there any relative? When headache mean there is tumor

Unclear question. Headache does not mean tumor. You should consult a dentist about your wisdom teeth as these may need to be removed. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex.
