What Not Brushing Before Bed Does to Your Teeth

/in /by

Picture this: it’s late at night after a long day, and you finally make it to bed. Just as you’re about to fall asleep, you remember — you forgot to brush your teeth. Skipping brushing before bed might not seem like a big deal, but for your dental health, it can be one of the worst habits you can form.

At Tim Chauvin DDS & Associates, we often see the effects of poor nighttime oral hygiene: cavities, gum disease, and even bad breath that could have been prevented. If brushing before bed feels hard to remember, here’s why it matters so much — and how to make it easier.

Why Brushing Before Bed Is So Important

When you eat, food particles and sugar fuel the bacteria in your mouth, causing them to multiply quickly. Those bacteria leave behind waste that turns into plaque. If you don’t brush it off before bed, plaque hardens into tartar overnight, which you can’t remove at home. Tartar buildup increases your risk for gum disease and cavities.

Think about that “morning breath” feeling when you wake up. If you skipped brushing, you’ve gone nearly twice as long between brushes, giving bacteria even more time to grow and leaving you with twice the germs.

Risks of Skipping Nighttime Brushing

Not brushing before bed can lead to:

  • Cavities and tooth decay

  • Gum inflammation or bleeding

  • Bad breath

  • Increased tartar buildup, which can only be removed by a professional cleaning

Nighttime is also when saliva production slows down, meaning your mouth has less natural protection against bacteria.

Create a Nightly Dental Routine

The American Dental Association recommends brushing at least twice a day for two minutes and flossing once daily. Spending those two minutes before bed removes harmful plaque and strengthens teeth — especially if you use fluoridated toothpaste.

Here are some tips to make brushing before bed easier:

  • Brush right after dinner if you’re likely to forget later.

  • Keep a toothbrush and toothpaste near your nightstand for a quick dry brush.

  • Try a new toothpaste or toothbrush that feels like a small “treat” so brushing feels enjoyable.

  • Pair brushing with another habit (like washing your face) so it becomes part of your bedtime routine.

Don’t Skip Dental Checkups

Even if you brush twice a day, regular dental visits are essential to catch problems early. If you notice tooth sensitivity, you may need a cleaning or treatment — read more about why teeth become sensitive here.
