Beyond Scaling: How to Get More From Your Ultrasonic

Do you really need your ultrasonic on 100%? (Probably not — and it may be costing you precision.)

Which part of the tip should actually be touching the tooth — and is that why the hygienists keep complaining about blunt tips?

Could the scaler tip you already own refine your margins, find a calcified canal and cut gutta-percha like a hot knife through butter?

And if you’re in the market for a new unit, which features are actually worth paying for?

Every dentist uses an ultrasonic — but most of us use it as a perio tool and nothing more. In this episode, Dr Hussain Hassanali, a general dentist who has gone properly geeky on ultrasonics, walks through how they really remove tooth tissue and how to put them to work in restorative dentistry and endo. It’s foundational, practical, and full of things you can try at your next session. Jaz’s biggest takeaway? Stop whacking the power up to 100%.

Protrusive Dental Pearl: Trim Gutta-Percha With Your Scaler Tip

You’ve just obturated a canal and need to remove the excess gutta-percha. The old ways: heat a ball burnisher in the flame until it glows red (that smell, and the GP smearing everywhere — or lifting out entirely because the sealer hasn’t set), or sink a long-neck bur into the GP while it spins and hope you don’t gouge the dentine.

Instead, take your bog-standard ultrasonic scaler tip, turn the water off, and set the power to around 10%. Sweep it across the orifice and it cuts through gutta-percha like a hot knife through butter — the water is off because here you want the heat. Then drop the power right down (around 2%) and gently compact the coronal GP, leaving roughly 1–1.5 mm of space for your restorative material to lock into the orifice. No flame, no burn risk, and a thin tip that doesn’t block your view. Try it once and you won’t go back to heated pluggers.
