About Sienna Smiles

A Dental Clinic Built Around One Idea.

Because when you actually understand what’s going on, the whole thing gets a lot less scary.

Our Story

Why We Do Things Differently.

Most of us have walked out of a dental appointment holding a treatment plan we didn’t quite follow, nodding along to words we weren’t sure about, too polite — or too anxious — to ask the question we actually needed answered. You leave knowing something is wrong, but not really knowing what. That gap is uncomfortable. For some people, it keeps them from coming back at all.

At Sienna Smiles, the appointment begins with making sure you can see exactly what your dentist sees. CBCT 3D imaging and intraoral scanning aren’t there to impress you — they’re there to put your own teeth, roots, and bone structure on a screen in front of you, in detail that makes the conversation real. When you can see what’s actually happening in your own mouth, a recommendation stops feeling like something being done to you and starts feeling like something you’re deciding together.

There’s a particular kind of relief that comes with genuinely understanding your own health. Not the relief of being reassured — the deeper kind, where you’ve seen the evidence, asked your questions, and made a decision that actually belongs to you. That’s what we’re trying to give every patient who walks through our door.

How We Work

Three Things That Feel the Same, Every Single Visit.

Not promises on a wall. Simply what you will notice from the moment you sit down.

No Surprises.

You will see exactly what we see — on screen, before anything is discussed. There is no moment of quietly agreeing to something you did not fully understand. You leave with it written down. That clarity is not a courtesy. It is the baseline.

Real Answers.

The question you hesitated to ask because it felt too simple — ask it. Every step of your examination is explained as it happens, in language that does not require a degree to follow. The particular unease of not knowing what is happening inside your own mouth tends to leave the room quickly.

Thorough Planning.

Before any procedure is scheduled, the plan already exists. Mapped out, discussed, understood by both of you. That preparation is what makes the appointment feel unhurried — not because time was rushed, but because nothing was left to chance beforehand.

The Practice

What You’ll Walk Into.

A calm, considered environment — designed to make appointments feel less clinical and more like a conversation.

The Team

Real People. Genuinely Care How You Leave.

Both dentists came to Sienna Smiles because they wanted to practise dentistry differently — the kind where you never feel rushed, where nothing gets recommended without a proper conversation first, and where you walk out feeling informed rather than just treated. That approach shapes every appointment here.

Dr Abhishek (Abhi) Singh is a dentist at Sienna Smiles. He holds a Bachelor of Dental Surgery (BDS) and has been registered with the Australian Health Practitioner Regulation Agency (AHPRA) under registration number DEN0001639626 since commencing practice in Australia in 2011. His registration can be verified on the AHPRA Register of Practitioners at ahpra.gov.au. With over 15 years of clinical experience, Dr Singh takes a diagnostic-first approach to treatment planning. He uses CBCT 3D imaging and digital intraoral scanning to assess dental and facial anatomy before any treatment recommendation is made. Patients see their own imaging on-screen during the consultation, and a written treatment plan with itemised costs is provided before any work proceeds. Dr Singh has clinical interests in [dental implant](/dental-implants) placement and restoration, [cosmetic dentistry](/cosmetic-dentistry) including [porcelain veneers](/porcelain-veneers) and composite bonding, and complex restorative cases such as full-mouth rehabilitation. He also mentors graduate dentists at Sienna Smiles — a role that reflects his commitment to evidence-based practice and continued professional development within the profession. Sienna Smiles is open Monday to Thursday 8:30 AM–6:00 PM, Friday 8:30 AM–5:00 PM, and Saturday 9:00 AM–3:00 PM. The practice is a preferred provider for HBF, HCF, and NIB health funds, and accepts all major health funds via HICAPS on-site processing.

Dr Alefia Boxwala is a dentist at Sienna Smiles. She completed her Bachelor of Dental Sciences (BDS) at M.A. Rangoonwala College of Dental Sciences and Research, Pune in 2012 and has been practising in Australia since 2018. She is registered with the Australian Health Practitioner Regulation Agency (AHPRA) under registration number DEN0002180562, verifiable on the AHPRA Register of Practitioners at ahpra.gov.au. Dr Boxwala is an active member of the Australian Dental Association (ADA) and has tutored candidates through ADA-accredited examinations — a role that reflects the clarity and thoroughness she applies to clinical reasoning and patient communication. Every consultation follows the same structure: each finding is shown on the intraoral camera and explained in plain language before any treatment is discussed. Her clinical interests include [restorative dentistry](/restorative-dentistry) (composite fillings, dental crowns, and bridges), [cosmetic dentistry](/cosmetic-dentistry) (professional [teeth whitening](/cosmetic-dentistry/teeth-whitening), porcelain veneers), and preventive care with a strong emphasis on patient education. For Dr Boxwala, education is not a pamphlet handed out at the end of an appointment — it is the structure of the appointment itself, with every finding discussed and every option outlined before a treatment plan is considered. New patients can book a consultation with Dr Boxwala at Sienna Smiles by calling 08 9455 1234 or [booking online](/book). The practice offers a [new patient check-up](/new-patients) for $299, which includes a comprehensive examination, professional clean, bitewing X-rays, and a written treatment plan.
