What Causes Tooth Problems?
Before we fix the problem, let’s see what makes teeth hurt:
- Sugar feeds bad bugs in your mouth
- Hard brushing can wear down teeth
- Acidic foods like lemon can hurt teeth
- Grinding teeth at night breaks them down
- Not enough brushing lets plaque build up
Over 90% of adults get tooth decay, and 1 in 8 people have sensitive teeth. But good news! Both problems can be fixed.
Daily Tooth Care Routine
Brushing Tips
The right way to brush makes a big difference! Here’s how:
- Use a soft-bristled toothbrush
- Hold brush at a 45-degree angle to your gums
- Brush gently in small circles
- Brush for two minutes, two times a day
- Don’t forget to clean your tongue
Important: Hard brushing increases gum problems by 27%! Always use a soft brush.
Best Toothpaste Choices
Not all toothpaste is the same. Look for these kinds:
- Fluoride toothpaste – stops 24% of cavities
- Potassium nitrate – helps with sensitivity
- Stannous fluoride – fights bacteria
- Nano-hydroxyapatite – fixes tiny holes in teeth
Flossing & Rinsing
Brushing alone misses 40% of your teeth surfaces! You need to:
- Floss between all teeth once daily
- Try a water flosser (removes 29% more plaque than string floss)
- Use alcohol-free mouthwash after brushing
Pro Tip: Floss, then brush, then rinse for best results!
Foods That Help or Hurt Teeth
What you eat changes your teeth a lot! Let’s look at good and bad foods:
Foods That Hurt Teeth
These foods can cause decay and sensitivity:
- Sugary treats (candy, cookies, cake)
- Acidic drinks (soda pop, sports drinks)
- Sticky foods (dried fruit, caramel)
- Very hot or cold foods (for sensitive teeth)
The WHO says we should eat less than 25g of sugar per day. More sugar means 114% higher risk of cavities!
Foods That Help Teeth
These foods make teeth stronger:
- Cheese and milk (has calcium)
- Leafy greens (full of vitamins)
- Crunchy vegetables (clean teeth naturally)
- Nuts (have minerals teeth need)
Also try xylitol gum after meals. It cuts cavity risk by 40% [^6].
Natural Ways to Help Teeth
You can use natural things to help your teeth!
Oil Pulling
Oil pulling uses coconut oil to clean your mouth:
- Put 1 tablespoon of coconut oil in your mouth
- Swish it around for 15-20 minutes
- Spit it out (not in sink!)
- Brush your teeth after
Studies show this can cut plaque by 50% in two weeks.
Dental Probiotics
Good bugs can fight bad bugs! Dental probiotics help:
- Balance mouth bacteria
- Fight bad breath
- Lower plaque
- Reduce gum problems
Custom dental guards can also help if you grind your teeth at night.

Questions People Often Ask
Can you fix early tooth decay?

No. Sensitivity can come from worn enamel, receding gums, or teeth grinding. But it’s good to check with your dentist.
Are natural toothpastes good enough?
Some are! Look for ones with nano-hydroxyapatite or xylitol. But many dentists still say fluoride works best.
How long until sensitivity toothpaste works?
Most people feel better after 2 weeks of daily use. Keep using it even after pain stops.
Can children get tooth sensitivity?
Yes, but it’s less common. Children can get sensitivity from cavities or worn enamel.
