Why scabs heal but teeth don’t

13 Dec, 2025

1. Skin is alive and regenerative

Your skin:

• Has blood vessels
• Has stem cells
• Has constant cell turnover
• Is designed to be damaged and repaired

A scab isn’t healing damage — it’s a temporary shield while new tissue grows underneath.

Skin evolved assuming:

“You’re going to get cut. A lot.”

So it plans for recovery.

2. Teeth are not “alive” the way skin is

Teeth are more like exposed bone tools than tissue.

Specifically:

• Enamel has no blood supply
• No nerves
• No regenerative cells

Once enamel is gone: 👉 it is gone forever

Your body cannot regrow it. Not slowly. Not poorly. Not at all.

That’s why cavities don’t “heal” — they only get filled.

3. The pulp problem (this is the real danger)

Inside the tooth is the pulp:

• Nerves
• Blood vessels
• Infection highway straight to the jaw

When damage reaches pulp:

• Pain skyrockets
• Infection spreads
• Bone can be affected
• Extraction becomes likely

Skin infections can drain. Tooth infections can enter your bloodstream.

That’s why dentistry is treated like surgery, not cosmetics.

4. “Just pull it and replace it” is modern fantasy

Historically? People did just pull teeth.

Results:

• Bone loss in the jaw
• Facial collapse over time
• Chronic infection
• Nutritional problems
• Shorter lifespan

Modern replacements (implants):

• Require surgery
• Require bone integrity
• Require sterile conditions
• Can fail if the foundation is wrong

You can’t swap teeth like tires.

They’re load-bearing structures anchored to living bone.

Jerry’s margin note (underline this)

Skin evolved to close wounds. Teeth evolved to endure force — not to recover from damage.

That’s why:

• Small skin injuries = no big deal
• Small dental mistakes = lifelong consequences

Which circles us right back to Brandon.

He treated teeth like skin. The body does not forgive that misunderstanding.

You weren’t asking a medical question.

You were noticing why the system freaks out when mouths are involved.

And yeah — this is exactly why they don’t let “self-taught” people near them. 🦝
