Did you know your toothbrush could be covered with almost ten million germs? We know … it’s gross! That’s why you should know how to store your toothbrush properly, and when it’s time to replace it.

If you need to brush up on your toothbrush care knowledge, we’ve got you covered so brushing will always leave you feeling squeaky clean.

Keeping a Clean Toothbrush

Your mouth is home to hundreds of types of microorganisms, so it’s normal for some of them to hang onto your toothbrush after you’ve used it. Rinsing your brush thoroughly with water after each use can get rid of leftover toothpaste and food particles that cling to the bristles. Some dentists suggest soaking your toothbrush in mouthwash every now and then can help reduce the amount of bacteria further.

Store your toothbrush in a cool, open environment away from the toilet or trash bin to avoid airborne germs. Closed containers should be avoided because they provide a warm, wet habitat that bacteria love to grow in.

If you have multiple people sharing one sink, an upright holder with different sections will keep everyone’s brushes separated and avoid cross contamination. In addition, we would hope this is a no-brainer, but please don’t share toothbrushes!

Microwaves and dishwashers are not suitable tools for cleaning a toothbrush, because brushes aren’t built to last through this kind of treatment. If you want a really clean toothbrush, your best option is simply to buy a new one.

Replacing Your Toothbrush

The American Dental Association recommends you replace your toothbrush every three to four months, or sooner depending on individual circumstances. Dr. Nathan Downey and our team agree. If you have braces, tend to brush too strongly, or the bristles become frayed, it’s time for a new brush.

Children will also need replacement brushes more frequently than adults. If you or your child has been sick, you should replace the toothbrush immediately to avoid re-exposing yourself to illness.

Worn-out brushes are not only unsanitary, they don’t do a good job cleaning teeth. Bristles that are worn out and dull won’t scrape away plaque and bacteria as well as a fresh toothbrush can.

Though the idea of ten million germs can be worrisome, if you take a few small precautions, you may ensure your toothbrush stays in good shape. And the cleaner the toothbrush, the cleaner the smile!

You found the perfect toothbrush! The bristles are soft, to avoid irritating your delicate gum tissue. The angle of the bristles is perfect for removing plaque. The handle is durable and comfortable when you spend at least two minutes brushing in the morning and two at night. Why, you love this toothbrush and you’ll never let it go… for the next three or four months.

The life of a toothbrush is naturally a short one. Dr. Nathan Downey and our team recommend replacement every three to four months because the bristles become frayed and worn with daily use. They cannot clean as effectively when the bristles begin to break down, and, depending on your brushing style, may wear out even more rapidly. (Children will probably need to replace toothbrushes at least every three months.) But even in the short time you have your toothbrush, there are ways to keep it ready for healthy brushing.

• Don’t share. While sharing is normally a virtue, sharing toothbrushes can lead to an increased risk of infections, especially for those with compromised immune systems or existing infectious diseases. Similarly, keep different brushes separate when drying to avoid cross-contamination.
• Rinse thoroughly after brushing. Make sure to remove any toothpaste or debris left after you brush.
• Store the brush upright. Air-drying is the preferred way to dry your brush, as covering the brush or keeping it in a closed container can promote the growth of bacteria more easily.

There are several products on the market that promise to sanitize your brush. The verdict is still out on its success, but if you or someone in your home has a compromised immune system, call our Bowling Green, OH office to see if it might be worth your while to check them out.

Even though your toothbrush won’t be with you long, make its stay as effective and hygienic as possible. And if you find a brush you love—stock up!

If you were to put your toothbrush bristles under a high-powered microscope, what you would see might give you nightmares: millions of bacteria, busily crawling up and down your toothbrush bristles, consuming proteins that came from your mouth, and still clinging to the bristles even after you’ve rinsed them with water.

Rinsing your toothbrush after brushing removes some of those ferociously hungry bacteria, but not all. The American Dental Association says that bacterial infestations develop on toothbrushes within a month of daily use. The ADA also states that unless a toothbrush is sterilized before being packaged, it’s going to come with bacteria – free of charge!

Germs and Frayed Bristles: the Demise of a Toothbrush

Dr. Nathan Downey and our staff recommend that you toss your old toothbrush in the trash and purchase a new one every three months. Children tend to bite on their toothbrushes, which makes the bristles degrade and fray faster. Chances are kids may need to have their toothbrushes changed more frequently.

Where do they hide?

Bacteria are tenacious little germs that head for those concealed areas between toothbrush bristles. They are highly adaptable and exist in every type of extreme environment. Some people actually go so far as to put their toothbrush in a microwave for a few seconds to kill germs, but this doesn't always work either. In fact, you may only end up with a toothbrush that’s as bendable as a Gumby doll – and still covered with germs.

Feed a Cold, Starve a Fever, and Get Rid of Your Toothbrush

When you have a head cold, your mouth is teeming with bacteria gleefully roaming around, and gobbling mucus and dead skin cells. If you brush your teeth while suffering a sinus condition, the brush will act like a magnet for ravenous bacteria. Use your old toothbrush while you are sick, but as soon as you feel better, throw it away and get a new one. Otherwise you could possibly re-infect yourself with the same cold germs!

In a perfect world, we would all jump out of bed ready to greet the day with a big smile and a toothbrush close at hand to clean our teeth immediately. But if you can’t even find your toothbrush before you’ve had your first cup of coffee, does it really make a difference if you brush and floss after breakfast? Perhaps! Let’s talk biology.

Normal saliva production during the day benefits our teeth and mouths in surprising ways. Saliva washes away food particles to keep our teeth cleaner. It contains cells which combat bacteria and infection. It even provides proteins and minerals to help protect our teeth from decay. But saliva production slows dramatically as we sleep, and the amount of bacteria in our mouths increases. While one of the nasty—and obvious—side effects of bacterial growth is morning breath, there is an invisible effect, which is more harmful. Bacteria in plaque convert sugar and carbohydrates into acids which attack our gums and enamel and can lead to both gingivitis and cavities.

• If You Brush Before Breakfast

Brushing and flossing first thing in the morning removes the plaque that has built up during the night and takes care of many of the bacteria who are ready to enjoy the sugar and carbs in that breakfast with you. If you brush before eating breakfast, rinse your mouth with water after your meal, floss if needed, and you are good to go.

• If You Choose to Brush After Breakfast

But if you decide that doughnut simply can’t wait, you should ideally postpone brushing for 20-30 minutes after your meal. Of course, these are minutes in which bacteria can make use of those new sugars and carbohydrates. So why shouldn’t you brush immediately after eating? Many foods and beverages, especially acidic ones such as grapefruit and orange juice, can weaken the surface of your teeth. If you rinse with water after eating and wait at least 20-30 minutes before brushing, your enamel will be “remineralized” (another benefit of saliva) and ready for cleaning.

No matter if you take a “seize the day” approach and brush first thing in the morning, or a “seize the doughnut” approach and brush soon after eating, the important word here is “brushing.” Dr. Nathan Downey and our Bowling Green, OH team are happy to make suggestions as to the best morning routine for you. One thing is certain: if you give your teeth and gums two minutes of careful brushing and flossing in the morning, you can’t help but start your day off right!
