Dental issues

Hello Doctor,
1.
I brush my teeth in two sessions.
Why is that? I first use toothpaste to brush my upper teeth, and after finishing, I use toothpaste to brush my lower teeth.
If I try to brush all at once, the toothpaste foam tends to flow out due to saliva, leaving me with only a little foam mixed with saliva on the toothbrush, which makes it feel like I'm not effectively cleaning my teeth.
What is the correct way to brush? Using my method takes a lot of time.
2.
I have been using my toothbrush for almost a semester, and there is a black discoloration at the base of the bristles that is difficult to remove.
It is said that toothbrushes should be replaced every three months.
Should I replace it if the bristles are not in good condition?
I look forward to your response.
Thank you.

Hello: It doesn't matter how many times you brush your teeth, but the principle is to ensure that the entire mouth is cleaned thoroughly.
Whether or not you use toothpaste is irrelevant as long as the teeth are cleaned properly; toothpaste is merely a flavoring agent and surfactant.
If the bristles at the base of the toothbrush appear black, it may indicate that the toothbrush is damp and has developed mold.
Therefore, after brushing, you should store the toothbrush upright with the bristles facing up to allow it to dry and prevent mold growth.
If the bristles become deformed, the toothbrush should be replaced.
Sincerely, Dr.

When it comes to dental care, proper brushing techniques and toothbrush maintenance are crucial for maintaining oral health. Let's address your concerns one by one.

1. Brushing Technique: It's common for people to divide their brushing into two parts, as you do. This method can be effective, especially if you find that the toothpaste foams too much and becomes diluted with saliva. However, the key is to ensure that you are using the right amount of toothpaste and employing effective brushing techniques. The American Dental Association (ADA) recommends using a pea-sized amount of fluoride toothpaste. When brushing, you should aim to spend at least two minutes total, ensuring that you brush all surfaces of your teeth: the outer, inner, and chewing surfaces.
If you find that the toothpaste is foaming too much, consider using a softer toothbrush or adjusting the amount of toothpaste you apply. Additionally, try to angle your toothbrush at 45 degrees to your gums and use gentle circular motions rather than aggressive scrubbing, which can lead to gum recession and enamel wear.
2. Toothbrush Maintenance: The presence of black spots on your toothbrush bristles can be concerning. These spots are often a result of bacteria or mold growth, especially if the toothbrush is stored in a damp environment. The ADA recommends replacing your toothbrush every three to four months, or sooner if the bristles are frayed. If your toothbrush has been used for a semester and shows signs of discoloration, it is advisable to replace it.
To maintain your toothbrush, rinse it thoroughly after each use to remove toothpaste and debris, and store it upright in a holder to allow it to air dry. Avoid covering your toothbrush or storing it in a closed container, as this can promote bacterial growth.
3. General Oral Hygiene Tips: In addition to proper brushing, consider incorporating flossing into your daily routine. Flossing helps remove plaque and food particles from between your teeth where your toothbrush may not reach. Mouthwash can also be beneficial, especially those containing fluoride, as it can help reduce plaque and prevent cavities.

4. Professional Dental Care: Regular dental check-ups are essential for maintaining oral health. Even if you feel that your brushing technique is adequate, a dentist can provide professional cleanings and identify any potential issues early on. If you have concerns about your oral hygiene routine or the condition of your teeth, don't hesitate to consult with a dental professional.

In summary, while your method of brushing in two parts is not uncommon, focusing on effective techniques and maintaining your toothbrush hygiene is essential. Replace your toothbrush regularly, use the right amount of toothpaste, and ensure you are brushing for an adequate amount of time. Incorporating flossing and regular dental visits will further enhance your oral health. If you have any persistent concerns, it's always best to consult with a dentist for personalized advice.
