There are some oral heath signs which should never be ignored, so pay close attention to these warning facts.
You noticed changes in the color and texture of gums/teeth
Oral health self examination is very important. Check closely for changes in the color of your gums, of your tongue, the interior of the cheeks or the mouth floor (below the tongue). If you notice that red or white patches have appeared, and these do not go way in about 14 days you should immediately get a thorough checkup at the dentist. White patches or wart like formations within the mouth could be indicative of oral cancer, so make sure to have these checked out by a specialist.
Catch dental decay early
If you notice any white spots forming on your teeth, these might be the first signs of dental decay. The hard enamel of the teeth starts dissolving because it is attacked by the acids which are produced by harmful bacteria. You can actually stop a dental decay/cavity from developing if you catch early these white spots.
Your teeth became more sensitive to hot and cold
This could mean two things. Your dental enamel got weaker which means you need a treatment with Calcium, or dental decay is trying to settle in. When dental decay has passed through the enamel and it tries to attack the nerve endings, you will feel an increased dental sensitivity. Make an appointment with the dentist and get those cavities treated before they can make further damage.
If dental sensitivity is caused by the fact that your enamel got weaker, this might mean you are grinding your teeth and they have worn down a lot. Get an appointment and tell the dentist to check for teeth grinding/clenching symptoms. You might have to wear a night mouth guard to stop your teeth from deteriorating further.
You have noticed that your gums have changed in texture
The natural and healthy color of the gums is a soft pink. If you noticed that your gums became red, a bit swollen and quite tender it is time for a dental checkup. Maybe you also noticed that your gums are bleeding while you are brushing, and this is the first sign of gingivitis.
Regardless of whether you feel any pain/discomfort or not, you need to get proper treatment, because gingivitis can easily turn into periodontal disease. If the inflammation spreads further and deeper into the gums, you could be at risk of losing your teeth.
Regular dental checkups help spotting any problem in its early stages. The dentist will clean professionally the plaque and tartar buildup, which are actually the main culprits in the development of gum disease. Also the dentist has a formed eye to spot any suspect changes within the tissue of the mouth which could be indicative of more serious problems.
