5 THINGS I NO LONGER BELIEVE - PART 1
After 28 years of practising dentistry, I’ve come to question many things I was taught.
Some of these opinions may be controversial.
But experience should make us more curious, not more certain.
Here are five beliefs I no longer accept without question.
❌ 1. STRAIGHT TEETH MEAN A HEALTHY MOUTH.
Straight teeth don’t automatically mean healthy breathing, swallowing, tongue function or sleep.
A beautiful smile doesn’t always tell the whole story.
❌ 2. WE SHOULD WAIT UNTIL ALL THE ADULT TEETH ERUPT BEFORE INTERVENING.
Growth doesn’t wait for us.
Some developing problems deserve attention much earlier.
Early assessment doesn’t always mean early treatment. But it gives us the opportunity to intervene when appropriate.
❌ 3. MECHANICAL JAW EXPANSION CORRECTS THE UNDERLYING DYSFUNCTIONS.
We can expand the maxilla.
We can create more space.
We can change the dental arch.
But what about the tongue that still rests low?
The mouth breathing?
The dysfunctional swallow?
The lips that still struggle to close?
Changing the structure doesn’t automatically correct the function.
Expansion can be valuable, but it isn’t a substitute for identifying and managing underlying dysfunctions.
❌ 4. BIGGER JAWS AUTOMATICALLY MEAN BETTER BREATHING.
An increase in anatomical dimensions doesn’t necessarily translate into better breathing or sleep.
We must distinguish structural changes from meaningful functional outcomes.
❌ 5. MORE FORCE MEANS BETTER RESULTS.
Biology doesn’t always respond better to greater force.
I increasingly believe in respecting growth, physiology and the body’s capacity to adapt.
SLOW AND GENTLE, AS NATURE INTENDED.
After 28 years, one thing has become increasingly clear to me:
WE SHOULD NEVER CONFUSE CHANGING ANATOMY WITH RESTORING FUNCTION.
And these are only the first five.
🔥 PART 2 IS COMING.
Next, I’ll share five more beliefs I’ve changed my mind about, including tongue-ties, mouth breathing and functional disorders.
