Your mouth is a complex part of your body. Many parts make it up, and each one works together to keep your oral health in great shape. That said, you might wonder exactly what each portion does and how you can take better care of them. Here are four sections of your oral anatomy that you should know and why they are important.

1.) Teeth

Teeth are often the star of the show. People typically have 32 in total, but some might be born with fewer or more. They are also broken up into four distinct types. From the center going out, you have your incisors, canines, premolars, and molars. They will help you tear your food and then grind it down. That way, your body will be able to better extract its nutrients. You also use them with your lips and tongue for clear speech.

The outer layer is your enamel, and it’s the strongest substance your body makes. However, it’s not invincible to damage. Plaque can erode it, so keep up with brushing and flossing to avoid problems.

2.) Gums

What holds your smile in place is your gums, or gingiva. They secure your teeth and protect the roots. When they are healthy, they are pink and firm, but bacteria can infect them and cause periodontal disease. If so, then these soft tissues may be noticeably red and inflamed. This condition can lead to tooth loss, so make sure you follow proper oral hygiene to prevent trouble.

3.) Tongue

You might be using your tongue to feel across your mouth. This muscular organ helps with chewing, speaking, and swallowing. It also has taste buds covering it, so you can detect different flavors. It can develop a white film, but this is a layer of bacteria.

By scrubbing it, you can return its natural pink color. If it’s discolored in any way, then you should talk to your dentist about it. That way, they can make sure your grin isn’t in trouble.

4.) Salivary Glands

If you look at your favorite food and your mouth starts watering, then you have your salivary glands to thank. They keep your oral cavity lubricated and produce saliva that aids in digestion. Not only that, but it can also remineralize your enamel and wash away harmful bacteria. So, it’s important to drink plenty of water to support it or eat crunchy fruits and vegetables to stimulate it.

There are many more parts to your smile, but your dentist is here to help you maintain them all. That way, you feel confident knowing your smile is well protected and stays in great shape.
