Four Ways Sleep Affects Your Oral Health

Every day at our Jacksonville, Florida dental practice we work hard to educate patients about their oral hygiene. We clean their teeth, fill cavities, place dental implants and other dental restorations, and teach them how they can keep their mouth, gums, and smile. healthy after they’ve gone home. One thing we don’t often mention in the dentistry office is to get more rest at night, but perhaps we should.

Rest may just be one of the most important aspects of good oral hygiene.

Why We Rest

Sleep is one of the most important functions of the human body. While it may seem like we’re not being productive during these night hours, our bodies are in fact restoring and repairing cells. Our brains store information we logged throughout the day, turning short term memory into long term. Vital functions like circulation, respiration, and digestion are slowed, giving the immune system a much needed break to replenish and restore at night. Sleep is also when we produce more hormones and synthesizes protein which enables us to recharge and ready ourselves, at a cellular level, for another day.

Sleep is as important to the human body as water and food, but it also plays a major role in oral hygiene as well. Here are four ways that rest impacts your oral health

Fights Infections

Sleep gives the immune system a chance to recharge at night, which is extremely helpful for oral hygiene. Scientific investigations have revealed that during a normal sleep cycle production of undifferentiated naive T cells and proinflammatory cytokines increase significantly. This means that while you rest your body’s system creates the cells dedicated to fighting infections and bacteria. These same studies also found that while you rest your immune system is “learning” how to fight the specific infection that plagues you and sending antigen specific T-cells to the source. Because the mouth is so full of bacteria at any given time, it is important that the immune system know how to fight off any infections that take hold. Sleep is key in keeping the immune system running strong and that is why it so beneficial for oral health.

Fortifies Teeth

Sleep is restorative for all the body’s systems and cells. While we rest at night, our cardiovascular system and blood vessels can be repaired from any damage sustained throughout the day. This translates into clear and strong pathways for essential nutrients, like calcium and phosphate, to make it to the bone tissue of the teeth for fortification. Rest is essential for maintenance of every cell and system in our bodies no matter if they are bones or soft tissues. While we snooze, our body is hard at work repairing structures and replenishing nutrients.  

Enables Development of Cavities

Sadly, sleep is not always the best for teeth either. As the body takes its well-deserved break, harmful bacteria can take advantage a vulnerable mouth. People who snore, or people who sleep with their mouths open are in particular danger of opportunistic bacteria. Saliva is one of the first lines of defense when it comes to clearing our mouths of harmful bacteria. When we rest with our mouths open or snore, the saliva dries up. This can allow harmful bacteria to begin digesting leftover sugars without reproach. This can lead to problems like acidification of the mouth and cavities. It’s difficult to ensure you keep your mouth closed while you are unconscious. So, to make sure your teeth are safe from bacteria while you rest is to brush and floss your teeth before bed.

Aside from enabling bacteria to begin the process of tooth decay sleeping can also cause your teeth to crack and break. Thankfully this is only true for people with bruxism, or people who grind their teeth at night. The cause for bruxism is largely due to stress. While the body is unconscious the brain will sometimes cause a person to begin to grind their teeth. The person has no idea that they are grinding their teeth and can do nothing to stop this from happening. If you have bruxism you can be fit with a custom night guard to cushion the pressure on your teeth and prevent cracking and fracturing of teeth.

Making the Most of Sleep

Sleep is one of the most good and important things we can give our body. It’s a time for cells to replenish and repair, and for your mouth to prepare for another day of smiling and eating. To get the best night rest for your body and teeth make sure to brush them for two minutes and floss right before your head hits the pillow. This will remove any sugar that could cause bacteria to feast. Also, wear any appliances, like night guards, to prevent any physical harm to your teeth.
