Nobody tells you this, but your hormones show up in your mouth. 🦷

20 years as a dentist and I see it every day. Your gums can feel different around your period. Pregnancy changes your teeth. Menopause can bring fragile gums and a burning tongue. Sjögren’s affects 9 in 10 women, and it’s often a dentist who spots it first. Even jaw pain (TMD) is linked to estrogen receptors.

I call this dentistry 2.0. The more we understand how our mouths and bodies connect, the healthier we can actually be.

How a dental cavity forms in less than 60 seconds 🦷

Think of your teeth like a bank account. They store minerals, and every snack or sip with carbs makes a withdrawal. Not just sugar. Bacteria turn it into acid that pulls minerals out of your enamel. Soft drink? Sugar plus acid, a double whammy.

Here's the part most people miss: the same biscuit can cost two people very different amounts. If your mouth is full of acid-making bacteria, you pay more for every snack. If you have a balanced microbiome, the good bacteria help neutralise the acid.

Comment DEPOSIT and I'll send you my guide to rebuilding your minerals 👇

Saliva, whole foods and remineralising products all make deposits. But deposits need time between snacks. Graze all day and the acid-makers never clock off, your account drops below zero, the enamel starts to break down, and a hole means a cavity.

20 years as a dentist, and these 5 products have been absolute game changers for my dental health. No gatekeeping. 🦷

1️⃣ MooGoo Moothpaste - Fluoride-free, with hydroxyapatite (the actual mineral your enamel is made of). I scanned it on Yuka and it came back a perfect 100/100.

2️⃣ Epic Gum - Sugar-free, xylitol gum that starves cavity-causing bacteria and boosts saliva flow.

3️⃣ Biome Dental Probiotic - One of my absolute favourites. Supports a healthy oral microbiome, reduces bad bacteria, and you wake up with fresher breath.

4️⃣ Tongue Scraper - Gentle enough to protect the bacteria on your tongue that make nitric oxide for your heart.

5️⃣ Crescent Nest toothbrush - A bamboo electric toothbrush that means far less plastic in your mouth and in landfill.

None of these are sponsored - just what's actually in my bathroom cabinet after 20 years of doing this.

Comment "FAVES" and I'll send you the full list 👇

20 years as a dentist, and I still get patients asking me: 'Why did I get this cavity?'

It should come as a shock - our teeth are strong. But here's the thing: the math around you getting a cavity just isn't mathing.

Comment CAVEMAN and I'll DM you my step by step guide to break in this cycle 👇

One filling can quietly turn into a root canal. A root canal can turn into an extraction. It doesn't happen overnight - but it can happen if we're not careful.

Caveman didn't have Colgate either, and yet here we are. So what's actually going on?

Your next supermarket trip could be doing more for your teeth than your toothbrush. Here’s what to grab:

🍵 Green tea - Contains EGCG, a compound that disarms cavity-causing bacteria

🥬 Beetroot & rocket - Packed with nitrate-reducing bacteria that help neutralise acid

🥩 Grass-fed meat & beef liver - Keeps your gums healthy

🥚 Eggs - The yolk is rich in vitamin D and vitamin A, without feeding cavity-causing bacteria

🥛 Plain yoghurt - Full of calcium and phosphate for your enamel (skip the sweetened ones)

🧀 Cheese - Neutralises acid and is packed with calcium and phosphate

🧈 Grass-fed butter - Helps drive that calcium into your teeth and your bones

None of these replace brushing, flossing or your regular check-up - but what’s in your trolley matters more than most people realise.

Your mouth isn’t just about teeth, it’s a window into what’s happening in the rest of your body. Here are 5 conditions that quietly show up in your mouth long before you’d notice them anywhere else:

Iron deficiency anemia - A smooth, pale tongue

Acid reflux - Eroded enamel on the back of your upper teeth

Sjögren’s syndrome - Dry mouth paired with dry, gritty eyes

Sleep apnoea - A scalloped tongue and flattened teeth from your jaw fighting to keep your airway open

Diabetes - Gum disease that won’t heal, no matter what you do

None of these are a diagnosis on their own, but they’re often the first visible clue - which is exactly why your six-monthly dental check matters for more than just your teeth.

We’re serious about wellness - not just teeth. Here’s what’s on offer at My Dentist Brisbane:

🔴 Red light therapy - Supports tissue healing and reduces inflammation

🫧 Ozone therapy - An antibacterial approach used alongside traditional treatment

🦷 Guided biofilm therapy - A deeper, gentler alternative to traditional scale and clean

🧬 Oral microbiome testing - Because your mouth bacteria say more than you’d think

💉 IV vitamin infusions - Nutrient support, same visit as your check-up

🫀 Vital pulp therapy - Save the nerve, avoid the root canal where possible

😮‍💨 Myofunctional orthodontics - Straightening teeth by addressing how you breathe and swallow
