When you brush your teeth, the temperature of the water is meaningless. The most important thing is using the correct technique. If you are unsure about the proper way to brush and floss, you should consult with your dental care provider.
Hot water keeps your teeth healthy and clean. It is important that you use warm water to keep your teeth healthy. And also, clean so you can enjoy that fresh, confident smile. Warm water has been shown to be twice as effective at cleaning teeth as cold tap water.
So, the temperature of the water used while brushing your teeth is all up to your personal preference – but never use “hot” water, you don't want to scald yourself. People with sensitive teeth, however, may want to use lukewarm water to help with the sensitivity that cold water may cause.
Yes, even cold water is bad for your teeth. Ice, in fact, is one of the absolute worst things you can subject your teeth to, and many people chew the ice cubes they use to chill their water with total disregard for the fact that they're damaging their teeth in multiple ways at once.
Proper Brushing Technique
Hold the bristles gently against the outside of your top teeth, near the gum line, at about a 45-degree angle upward. Sweep the brush gently back and forth over teeth and gums in soft strokes — or, if you prefer, use an elliptical (circular) motion to clean the teeth.
The brushing method recommended to general persons in Korea is the 3-3-3 brushing method campaign, which involves only toothbrushing behavior (the time and frequency); 3-3-3 means brushing one's teeth 3 times per day, within 3 minutes after having a meal, for at least 3 minutes each time.
The American Dental Association (ADA) recommends the 2/2 rule: brush for 2 minutes in the morning and 2 minutes at night with a soft-bristled toothbrush and fluoride toothpaste.
Filtered tap water and bottled water with a healthy pH level will pose no problems for your teeth. Plus, staying hydrated allows you to produce healthy amounts of saliva. Tap water containing fluoride, which is fairly common today, has the added benefit of strengthening the enamel of your teeth.
Generally speaking, drinking icy cold water should not damage your teeth. However, for those with sensitive teeth or exposed roots, extreme temperatures can cause discomfort or even increase the risk of tooth decay if consumed frequently.
A large change in mouth temperature may also cause your teeth to crack, such as eating hot soup and then drinking cold water right afterward. Teeth that have large restorations may be susceptible to fracture as the restoration weakens the tooth structure.
Dr. Price suggested that water that is too warm may soften some toothbrush bristles, making them less effective, and that water that sits in a hot water tank or lead pipes may collect harmful metals and other chemicals.
One expert, professor Damien Walmsley of the British Dental Association, said, “A dry brush will increase friction with the bristles while a wet toothbrush adds moisture and for most people, makes the experience more pleasant.
In most cases, it's best to brush your teeth before breakfast. This ensures that your enamel is protected and that you don't run out of time before leaving the house for work or school. Sugar-free gum is a great way to clean your teeth and achieve fresh breath after breakfast while also supporting a healthy smile.
If you are experiencing a severe toothache the best thing is ice water in the mouth. You may have gasses trapped in your tooth. If you keep ice cold water in your mouth, the gasses will contract and pain either lessens or ceases.
The germs and bacteria inside your mouth multiply during the night. When you drink water in the morning before brushing, it will clean out your mouth and make tooth-brushing more effective. When you make a habit of drinking water before brushing, you will notice your immunity becoming more robust.
Short answer: no, you should not rinse your mouth immediately after brushing your teeth. Most toothpastes contain an active ingredient called fluoride, which is a mineral that helps prevent tooth decay. When you rinse with water after brushing, you're prematurely washing out the fluoride that's working on your teeth.
Brushes with medium or hard bristles used with some force can remove the protective enamel coating your teeth. This results in sensitive teeth and gums that hurt when you drink something cold.
According to Sanda Moldovan, MS, DDS, warm water is better for the teeth and restorations, and is more easily absorbed.
That's because, over time, your protective layer of tooth enamel can wear down, exposing the soft, inner part of your tooth called dentin, where the nerves live. Certain triggers—including cold foods, drinks, or even a burst of air—can aggravate the nerves, causing a short, sharp pain, also known as tooth sensitivity.
Water can naturally wash away unwanted food particles and sugar that sticks to your teeth after eating—it kind of acts like a natural toothbrush. Swishing water after meals is a great way to do this, but simply drinking water throughout the day is also important to keep the teeth clean and prevent cavities.
You should refrain from brushing more than three times a day, because brushing too often will wear down the enamel of your teeth. You must brush at least twice, but not more than three times a day.
Brushing twice daily is crucial because it helps prevent tooth decay and cavities. Therefore brushing is not designed to whiten teeth, and even using whitening toothpaste will not deliver the desired results.
