Brushing your teeth before bed is a mistake! This is when you really need to brush your teeth

Many people tend to wait until right before bedtime to brush their teeth, but this habit is actually not ideal—especially for those who struggle with falling asleep. Brushing your teeth, particularly with toothpaste containing mint, can stimulate brain activity and dispel the sleepiness that’s been building up throughout the day.

Instead, it's recommended to brush your teeth 30 minutes to 1 hour after dinner. This not only helps protect your teeth effectively but also acts as a calming ritual, helping your body and mind ease into the evening. Also, avoid eating or drinking sugary items before bed.


Why you shouldn't brush right after eating

The normal pH in the mouth is around 6.6–7.1. Studies show that after eating, the pH in your mouth drops—acidifying—and reaches its lowest point around 12 minutes post-meal. It then gradually returns to normal after about 30 minutes.

If you brush your teeth too soon after eating, you're doing it while your mouth is still acidic. In that state, the enamel minerals are more easily dissolved, and brushing can wash those minerals away—potentially weakening your teeth over time.

That’s why brushing 30–60 minutes after a meal is scientifically considered the best practice.


Common Toothbrushing Mistakes

1. Brushing horizontally

Brushing back-and-forth too hard or for a long time, especially with hard bristles, can cause abrasion at the gumline. Enamel is the hardest tissue in the body, but it’s thinnest at the neck of the tooth—making this area vulnerable to wear.


2. Brushing too briefly

Due to rushed mornings or laziness at night, some people brush for only a few seconds. Ideally, brushing should last at least 3 minutes to clean all surfaces properly.


3. Neglecting the tongue

The tongue’s uneven surface harbors bacteria that can lead to bad breath and oral infections. Cleaning your tongue regularly—using a soft toothbrush or tongue scraper—can help reduce this bacterial buildup.


4. Not replacing your toothbrush often enough

Toothbrushes can accumulate germs, mold, and bacteria over time. Frayed bristles also lose cleaning effectiveness and can harm gums. You should replace your toothbrush every 3 months, or sooner if the bristles are worn out.


 How to Brush Your Teeth Properly

Using the modified Bass technique (small circular motions at a 45-degree angle) is recommended:

  • Outer surface of front teeth: Hold the brush at a 45° angle to the gumline and move it in small circles.

  • Inner surface of front teeth: Use the same 45° angle—gently brush upward for the lower jaw and downward for the upper jaw.

  • Chewing surface: Brush back and forth gently with the brush flat on the surface.

  • Inner surface (vertical strokes): Hold the brush upright and gently move it in small up-and-down motions.

Work on 2–3 teeth at a time, repeating the motion 8–10 times, covering all surfaces: outer, inner, and chewing.


 Tips for Choosing the Right Toothbrush

  • People with healthy teeth and gums: Choose a soft or medium-soft bristle brush with a small head for better access.

  • Elderly individuals or those with gum disease: Consider using extra-soft bristles or an electric toothbrush.

  • To clean your tongue: Use a dedicated tongue scraper or a toothbrush with a soft-textured back.
