Mouth, Teeth & Gums

Tooth Decay

Erosion of tooth enamel and dentin by acid-producing bacteria feeding on sugars — nearly universal in Western populations but preventable through eliminating sugar and acidic drinks, eating raw fruits and vegetables, calcium supplementation, and rigorous oral hygiene.

📝 Summary

In short: Erosion of tooth enamel and dentin by acid-producing bacteria feeding on sugars — nearly universal in Western populations but preventable through eliminating sugar and acidic drinks, eating raw fruits and vegetables, calcium supplementation, and rigorous oral hygiene.

Common causes: Sugar and sticky sweet foods (bacteria produce acid as they metabolize sugar); Cola and carbonated drinks (phosphoric acid + sugar — directly dissolves enamel); White flour products (sticky, cling to teeth).

First thing to try: ELIMINATE the primary causes: no cola drinks, no sticky sweets, no white sugar products

See a doctor if: For any toothache indicating the decay has reached the nerve, or for cavities identified in dental X-rays.

🌿 Overview

An estimated 98% of Americans have dental cavities, yet populations that have never eaten Western foods have essentially none. This contrast reveals tooth decay as almost entirely diet-driven. Plaque (a sticky bacterial film) forms on the tooth surface; when bacteria feed on sugars they produce acids that dissolve the hard enamel, then the softer dentin beneath. Cola drinks are especially destructive — they contain phosphoric acid and sugar, and the acid directly dissolves tooth structure. If decay reaches the nerve (tooth pulp), pain begins. The disease is almost entirely preventable.

Common signs

  • Initial stage: no pain or symptoms
  • Visible cavity or dark spot on the tooth surface
  • Sensitivity to hot, cold, or sweet foods as decay deepens
  • Pain beginning when decay reaches the nerve (pulp)
  • Toothache when chewing

🔎 Why it happens

Common causes and triggers — spotting yours is often the first step to relief.

  • Sugar and sticky sweet foods (bacteria produce acid as they metabolize sugar)
  • Cola and carbonated drinks (phosphoric acid + sugar — directly dissolves enamel)
  • White flour products (sticky, cling to teeth)
  • Soft, gooey, and processed foods
  • Dairy products (especially soft cheeses)
  • Poor oral hygiene (allows plaque to accumulate)
  • Calcium and vitamin D deficiency

✅ What to do

Gentle, practical steps you can take at home — start at the top.

  1. ELIMINATE the primary causes: no cola drinks, no sticky sweets, no white sugar products
  2. Rinse mouth after every meal — or finish a fruit meal by eating an apple (natural teeth-cleanser)
  3. Brush carefully after each meal (soft brush, move from root to tip of tooth, gentle strokes at gumline)
  4. Floss faithfully
  5. Use an electric toothbrush — removes 98% of plaque vs. 48% for a regular toothbrush
  6. CALCIUM supplementation — vital for maintaining tooth and bone structure; needs increase with age
  7. Eat raw fruits and vegetables: leafy greens, raw carrots, parsley, turnip greens, garbanzo beans, whole grains, nuts, and legumes
  8. Strawberries: rub halves on teeth — natural tooth cleanser
  9. To remove tartar: mix equal parts cream of tartar + sea salt (or baking soda + sea salt)
  10. ANTI-BACTERIAL HERBS: Bloodroot (reduces plaque); bay leaf (contains cineole — kills dental bacteria); licorice (glycyrrhizin and indole — kills bacteria); wild bergamot (thymol and geraniol — prevents decay)
  11. Goldenseal extract (alcohol-free): use as antibacterial mouthwash
  12. Massage gums daily with finger
  13. AVOID: rhubarb, poke, and spinach (high oxalic acid, inhibits calcium formation)
  14. AVOID: commercial toothpastes and powders (detergents are harmful to teeth and gums)

🍽️ Eating to help

Food is one of the gentlest medicines — small, steady changes help most.

Favor these

  • Raw fruits and vegetables (cleanse and exercise teeth)
  • Whole grains, nuts, and legumes
  • Calcium-rich plant foods
  • Clean water (rinse the mouth)

Go easy on

  • Cola and carbonated drinks (phosphoric acid dissolves enamel — most destructive)
  • Sugar and sugary foods (feeds plaque bacteria)
  • Sticky foods and candies
  • White flour products
  • Soft cheeses and dairy products
  • Chewable vitamin C tablets (acid damages enamel)

Drop a tooth into a glass of Coca-Cola and watch how many hours it takes to completely dissolve — this demonstrates what cola drinks do to teeth over years of daily consumption.

⚖️ Good to know

  • Avoid fluoride treatments — the encyclopedia recommends politely declining fluoride from your dentist
  • Avoid mercury (amalgam) fillings — mercury is a poison; request composite (plastic) or ceramic alternatives
  • Once decay reaches the pulp (nerve), professional dental care is required — the pain is severe
  • Air abrasion technology is a modern option for painless removal of decay without drilling

🩺 When to see a doctor

  • For any toothache indicating the decay has reached the nerve, or for cavities identified in dental X-rays.
  • Routine dental checkups help catch decay early, before it becomes painful.
