Many people think that small bumps on the gums do not affect eating and drinking and are not a big deal. In fact, this is often an early symptom of gum cancer, which can be better treated if it can be treated urgently. 1. Most of the early gum cancers have no conscious symptoms. At first, ulcers, papillae or nodular lumps occur on the gums, which bleed easily, and if they extend to the alveolar process, teeth will be painful, loose or fall off. When secondary infection occurs, it produces severe pain and causes local bleeding and foul smell. 2.The symptoms of early gum cancer and periodontitis are similar, both teeth will be loose and painful, but the reasons are fundamentally different. Gum cancer is the tendency of gum mucosa to thicken and ulcerate, while periodontitis is mainly the overflow of pus from periodontal pockets, resorption of alveolar bone, swelling of gums and smooth mucosa without proliferation. In many clinical cases, gum cancer is misdiagnosed as periodontitis and teeth are extracted, resulting in unhealed trauma and accelerated tumor growth. 3. Any unexplained gum mass, erosion or toothache accompanied by loose teeth, long-term non-healing of the wound after tooth extraction or crater-like (crater-like) ulcers on the gums, especially for those who are over 40 years old, should go to a regular hospital for examination in a timely manner. Usually, do not pick the new lumps on the gums with your fingers or toothbrush to avoid infection and aggravation of the disease. 4.To prevent gum cancer, first of all, pay attention to oral hygiene and go to hospital for examination once every six months or once a year regularly, and secondly, eliminate some bad chronic stimuli in time, such as extracting residual root, residual crown and misaligned teeth, grinding off sharp tooth tips and removing unsuitable dentures. Change the habit of eating too hot, quit smoking and drinking, and reduce the exposure to harmful substances. If you find erythema, white spots, flat Taiwan ringworm and long-term untreated chronic ulcers in the mouth, you should be alert to achieve early diagnosis and treatment. The difference between gingivitis and gum cancer The symptoms of gingivitis are usually bright red or purplish red, swollen and soft gums, sometimes there is erosion of gingival edge or the growth of inner buds and ectopia, the gums tend to bleed when brushing or eating, but generally there is no spontaneous bleeding, the patient has no obvious conscious symptoms, sometimes there may be itchy or swollen feeling, and the bad breath is obvious. Gum cancer is mostly manifested as gum ulcers, painful loose teeth, and swollen lymph nodes in the submandibular and other areas can be seen when lymph node metastasis occurs. Gum cancer is mainly caused by the presence of foreign bodies in the gum margin and long-term failure to clean it, which is the result of long-term bacterial growth and stimulation; in addition, with age, more or less atrophy will occur, exposing the roots of teeth, which is called physiological atrophy and does not require treatment. Then there are the sequelae of improper dental surgery. Keeping your teeth clean is the most effective way to slow down gum recession, and regular scaling is especially important. Inflammatory gum recession is mainly characterized by red, swollen and painful gums, and bleeding when brushing. Gum recession in the elderly often makes the exposed tooth poles unusually sensitive to hot and cold temperature changes and acidic foods, which hinders eating and reduces the quality of life, so special attention should be paid to prevention and treatment. Although the main symptoms of gingivitis and gum cancer are similar, gingivitis is caused by inflammatory infection and has a shorter course. Gum cancer is a cancerous mass and has a longer course. It is recommended to take a biopsy for pathology to clarify the nature of the lesion and decide the treatment plan under the guidance of the doctor according to the examination results.
