What are the symptoms of a tooth infection?

by | 5 May 2026

A tooth infection (also called a dental abscess) happens when bacteria infect the pulp inside your tooth. It won’t go away on its own — and early treatment is important.

Common Symptoms:

  •  Severe, throbbing toothache (may spread to jaw, ear, or neck)
  •  Pain when chewing or biting
  •  Sensitivity to hot or cold that lingers
  •  Swollen gums or a pimple-like bump on the gums
  •  Facial or jaw swelling
  •  Bad taste in your mouth or bad breath
  •  Fever or feeling unwell

Seek urgent dental care if you notice:

  • Difficulty swallowing or breathing
  • Swelling spreading to your eye or neck
  • High fever

A tooth infection is a dental emergency — the sooner it’s treated, the easier (and less painful) it is to fix.

How can I prevent getting cavities and decay?

Cavities happen when bacteria feed on sugars and produce acids that weaken your enamel — but the good news is they’re largely preventable!

     1. Brush Properly (Twice a Day)

  • Use fluoride toothpaste
  • Brush for 2 full minutes
  • Don’t forget the gumline and back teeth

 2. Floss Daily

Your toothbrush can’t clean between teeth — floss removes plaque where cavities often start.

3. Watch Sugary & Acidic Foods

  • Limit sweets, soda, sports drinks, and frequent snacking
  • Rinse with water after eating
  • Avoid sipping sugary drinks throughout the day

 4. Get Regular Dental Check-Ups

Professional cleanings remove hardened plaque (tartar) you can’t brush away at home.

5. Strengthen Your Enamel

  • Drink fluoridated water
  • Ask your dentist about fluoride treatments or sealants (especially for kids)

Bonus Tip:

Chewing sugar-free gum after meals can help increase saliva and wash away acids.

What is the best way to prevent cavities in children?

Cavities are very common in kids — but the good news is they’re highly preventable with simple daily habits.

 1. Start Early & Brush Properly

  • Clean your baby’s gums even before teeth appear.
  • Begin brushing as soon as the first tooth erupts.
  • Use a smear (rice-sized) amount of fluoride toothpaste under age 3.
  • Use a pea-sized amount from ages 3–6.
  • Parents should supervise brushing until about age 7–8.

 2. Limit Sugar

  • Reduce sugary snacks, candy, and sticky foods.
  • Avoid frequent sipping of juice or sweet drinks.
  • Encourage water between meals.
  • Don’t put children to bed with milk or juice bottles.

 3. Visit the Dentist Regularly

  • Schedule the first dental visit by age 1.
  • Keep up with check-ups every 6 months.
  • Ask about fluoride treatments and dental sealants for molars.

Why It Matters

Healthy baby teeth are important for proper chewing, speech development, and guiding permanent teeth into place.

Are sweets bad for my teeth?

Short answer: Yes — but it’s about how and how often you eat them.

 Why sweets can cause cavities:

  • Sugar feeds the bacteria in your mouth.
  • These bacteria produce acid.
  • The acid weakens enamel and leads to tooth decay.

 Frequency matters more than quantity

Eating sweets occasionally with meals is less harmful than snacking on them all day. Constant sugar exposure keeps acid attacking your teeth.

 Sticky sweets are worse

Caramels, gummies, and lollipops cling to teeth longer, increasing the risk of cavities.


 How to enjoy sweets safely:

✔ Have them with meals, not as frequent snacks
✔ Rinse your mouth with water afterward
✔ Wait 30 minutes before brushing (especially after acidic foods)
✔ Brush twice daily with fluoride toothpaste
✔ Keep up with regular dental check-ups

You don’t have to give up sweets completely — just be smart about them!
