Ever felt that sharp zing from hot coffee, ice cream, or even just breathing in cold air? Tooth sensitivity isnāt randomāitās your teeth trying to tell you something.
- Your enamel might be wearing down.
- Your gums might be receding.
- You could be grinding your teeth at night without realizing it.
Most people grab Sensodyne and call it a day. But numbing the pain doesnāt solve the problemāit just masks it.
Instead, hereās exactly what I do when I notice my teeth getting a little sensitive:
1. I Run Through My āWhatās Causing This?ā Checklist
Sensitivity doesnāt happen randomly. I stop and ask myself:
Am I brushing too hard in one spot?Ā (I check my technique for overbrushing, which can be a difficult habit to breakāthis is a big one.)
Did I forget to replace my toothbrush head this month?Ā (I swap mine out every month, but if I slip up, Iāll notice my teeth feeling it.)
Have I been eating more acidic foods than usual?Ā (Even āhealthyā drinks like kombucha and sparkling water can wear down enamel.)
If I catch myself doing any of these, I adjust immediately.

2. I Use Fygg Varnish to Reverse Sensitivity Fast
If my teeth ever feel sensitive, I know itās a sign that my enamel needs support. Thatās why I useĀ Fygg Varnish.
Nano-hydroxyapatite works just like fluoride to remineralize teeth, but itāsĀ a safer, biomimetic alternativeābecause itās the same mineral your enamel is actually made of.
The key to reducing sensitivity is sealing those open dentinal tubules, and thatās exactly what Fygg Varnish does.
Hereās how I use it:
- I apply a thin layer inside my trays.
- I wear them for one hour to give my teeth time to absorb the nano-HAp.
- Over time, I notice stronger, less sensitive teethāsometimes even after a single use.
- Before I pop them in, I make sure that my mouth is totally clean (brush, floss, tongue scrape) so that everything is clean and exposed to the varnish.
I formulatedĀ Fygg VarnishĀ because nothing else worked the way I needed it to.Ā Itās my go-to for remineralization, and I recommend it to anyone dealing with sensitivity.
3. I Support My Teeth from the Inside Out with Magnesium
I think itās crazy that we dentistsĀ are still recommending Sensodyne, but almost no one is talking about magnesium.
Magnesium is essential for strong, healthy teeth.Ā Without it, your bodyĀ canāt properly regulate calcium and phosphate,Ā which are critical for enamel strength. It also plays a role in:
- Supporting remineralizationĀ by balancing calcium and phosphate levels.
- Reducing inflammation, which is important if gum recession is part of the problem.
- Relaxing muscles and the nervous system,Ā which may help reduce teeth grindingāa hidden cause of sensitivity.
I take Magnesium Breakthrough daily, because youĀ cannotĀ build strong teeth without it.
šĀ Want stronger, less sensitive teeth?Ā This is the magnesium I trust.
4. I Make Sure My Saliva Is Doing Its Job
Most people donāt realize that saliva is one of the most important factors in protecting your teeth. Itās not just there to keep your mouth moistāitās constantly working to:
- Neutralize acids that wear down enamel
- Deliver calcium and phosphate to remineralize your teeth
- Seal dentin tubules to reduce sensitivity
If my teeth feel more sensitive than usual, I stop and think: Is my saliva doing what itās supposed to?
Hereās what I do to keep it working optimally:
- I breathe through my nose. Mouth breathing dries out saliva, which makes teeth more vulnerable. If I catch myself mouth breathing at night, I use mouth tape.
- I stay hydrated. Saliva is 99% water, so if Iām dehydrated, my teeth pay the price.
- I use the right toothpaste. Fluoride and nano-hydroxyapatite both remineralize, but nano-HAp is what my teeth are actually made of. Thatās why I formulatedĀ FyggĀ Toothpasteābecause nothing else on the market worked the way I wanted it to.

5. I Use the Safer, More Effective Alternative to Fluoride
Fluoride worksāthereās no debate about that. But nano-hydroxyapatite works just as well, and itās biomimetic, meaning your body actually recognizes it as a natural part of your teeth.
A clinical trial comparing nano-HAp and fluoride toothpaste found that both reduced sensitivity, but nano-HAp actually repaired enamel better.
The difference?
- Fluoride makes enamel more acid-resistant but doesnāt replace lost minerals.
- Nano-hydroxyapatite fills in and repairs damaged enamel, literally replacing whatās been lost.
- It also seals dentinal tubules, reducing sensitivity at the source.
So hereās my question:Ā Why are we still recommending Sensodyne when we have solutions like nano-hydroxyapatite and essential minerals like magnesium?
Give this a try, and let me know how it works for you.
