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 Canadian Dental Association says that bacterial infestations develop on toothbrushes within a month of daily use. The CDA 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. Organ, Dr. Kirtane, and Dr. Hart 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!

Many people who are careful about brushing and flossing their teeth wonder how they still end up with cavities or tooth decay. Several factors affect wear and tear on tooth enamel. Diet is a major factor, with certain foods increasing the likelihood that your enamel will become discolored or decayed. Pay close attention to the foods you eat to keep your pearly whites looking healthy and clean.

What causes enamel damage?

Tooth enamel refers to the hard, semi-translucent, whitish part of the tooth that shows above your gums. The enamel is primarily composed of minerals that are strong but susceptible to highly acidic foods. When acid reacts with the minerals in enamel, it results in tooth decay. Strongly pigmented foods can also damage enamel by discoloring the surface of the tooth.

Foods that harm enamel

Acidic foods are the greatest source of enamel damage. To determine whether a food is acidic, look up its pH. Scientists use pH, on a one-to-seven scale, to define the relative acidity or alkalinity of a substance. Foods with low pH levels, between a one and three, are high in acidity and may damage your enamel. Foods with high pH levels, such as a six or seven, are far less likely to cause enamel harm.

So which foods should you avoid? Many fruits are high in acidity, including lemons, grapefruit, strawberries, grapes, and apples. The high sugar and acid content in soda makes it another huge contributor to enamel decay. Moderately acidic foods include pineapple, oranges, tomatoes, cottage cheese, maple syrup, yogurt, raisins, pickles, and honey. The foods that are least likely to cause enamel damage include milk, most cheeses, eggs, and water.

Beverages such as red wine and coffee also damage the enamel by discoloring it. Although stains do not necessarily undermine the integrity of your teeth, they can be unsightly.

What can I do to prevent enamel damage?

Fortunately, there are several measures you can take to prevent your enamel from discoloring or decaying. The easiest way to avoid decay is to steer clear of high-acidity foods. This may not always be possible, but eliminating sugary fruit juices and soda from your diet is a good start. Brushing your teeth after each meal and flossing frequently also preserves your enamel. Another good idea is to rinse your mouth with water or mouthwash after eating to wash away high-acidity particles.

Although enamel damage is common, it does not have to be an inevitable occurrence. Knowing the foods that harm your teeth gives you the tools to prevent discoloration and decay. With some easy preventive measures, your teeth will stay strong and white for years to come! Give us a call at Hamilton Orthodontics to learn more!

This may come as a surprise, but brushing your teeth right after a meal can be one of the worst things you can do for your healthy teeth. A toothbrush can be considered an assault weapon against your smile if used immediately after eating certain foods.

Enamel is like the tooth’s shield. It is a hard mineral exterior on each of your teeth. In reality, enamel is the hardest part of the human body—even stronger than bone! I like to regard it as a “super-structure.” But every superhero has a weakness, and enamel’s kryptonite is acid.

A healthy tooth lives in a mouth that has a proper pH balance. When that balance tips from alkaline to acidic, a harmful process called demineralization begins. Demineralization occurs when acids attack and soften the tooth surface. Pores and fissures form and harmful bacteria move in.

With each bite of food or drink, our mouth pH fluctuates. Highly acidic foods tip the balance of your mouth from a healthy alkaline to a dangerous acid. Here are some examples of those sources of acid: citrus fruits, soda, and sugary foods. There are certainly many others, but these are the most common.

So how does brushing your teeth immediately after a meal make this process even worse?

After eating highly acidic foods, your teeth are susceptible to damage. When you brush your teeth in this weakened state you are actually damaging your enamel. The abrasive bristles of the brush wear away the protective surface of the teeth. You should avoid brushing for at least an hour, or take other, simple preventive measures immediately following a meal.

First, rinse with or drink clear water. Then chew some sugarless gum. Both of these practices will produce saliva, restore a healthy pH level in your mouth, and coat your teeth with nourishing minerals. Out of all the sugarless gums available, the best of the best are those that list xylitol as the first ingredient. Another option is to consume cheese, milk, or another non-acidic food or drink to conclude your meal.

After you have given your mouth time to return to a healthy pH, feel free to brush your teeth. Just keep in mind that any time you eat acidic foods, you weaken your teeth. Make sure not to worsen the problem by brushing immediately after dining and damaging your teeth even more. Questions? Call us at Hamilton Orthodontics.
