Gum disease affects the tissues surrounding the teeth and can lead to serious health problems if not treated properly. It is important to detect any early signs of gum disease to treat it before it gets worse. Some signs to watch out for include:

1. Bleeding: Bleeding is one of the most common signs of gum disease, and it occurs when brushing your teeth or eating.

2. Redness and swelling: The gums may appear swollen, red, and painful, and feel swollen and warm to the touch.

3. Bad breath: A person suffering from gum disease may have bad breath caused by bacteria that build up in the mouth.

4. Receding gums: Gum disease can cause gums to recede and reveal long, sensitive teeth.

5. Pain: A person with gum disease may feel pain when touched or when eating.

6. Tooth loss: If left untreated, gum disease can eventually lead to tooth loss.

Once you notice any of these signs, you should talk to your dentist to diagnose and treat gum disease. It is important to pay attention to oral and dental hygiene and healthy nutrition to prevent gum infections and other oral infections.
