Have you ever looked back at a photo and noticed more gum than teeth when you smile? It's one of the more common cosmetic concerns people bring to us, and it rarely means anything is wrong. A gummy smile simply describes a smile where the gums show more than you'd like, throwing off the balance between your gums, teeth and lips. The reassuring part is that it can usually be improved, and often more simply than people expect. 

Here's how to fix a gummy smile, and how to work out which option actually suits you.

First, What Counts as a Gummy Smile?

There's no exact cutoff, but dentists often describe a smile as gummy when more than about three to four millimetres of gum shows above the top teeth. Some people notice it all the time. Others only spot it in photos or when they laugh. Either way, it's a cosmetic thing rather than a health problem. Your teeth can be perfectly healthy and still sit behind a gumline that shows more than you'd like.

Why the Cause Decides the Fix

Here's the part that catches most people out: a gummy smile isn't a single problem, so there isn't a single fix. What looks like "too much gum" can come from a few different places:

• gums that sit low over otherwise healthy teeth

• teeth that look short or small for your face

• an upper lip that lifts higher than average when you smile

• the position of your teeth or the way your bite meets

• teeth that never fully came through

Because the cause differs from person to person, so does the right treatment. That's why a proper look comes first, so you're not paying for a fix that was never going to address the real reason. The options below are grouped by the cause they suit best.

If It's Mostly Your Gums: Gum Reshaping

When healthy teeth are partly hidden under gum that sits too low, gum reshaping (also called gum contouring) is often the most direct answer. Using a dental laser or fine instruments, the excess gum tissue is carefully trimmed and reshaped to reveal more of the natural tooth and even out your gumline. It's usually done under local anaesthetic, and many people are back to their day within a day or two. 

For a lot of patients looking into cosmetic gum treatment, this is the simplest place to start, and it's a common first step in gum reshaping around Homebush West.

If Your Teeth Look Short or Uneven: Veneers or Crowns

Sometimes the gums are fine, and it's the teeth that look a little short, which makes the gums seem more prominent by comparison. Porcelain veneers are thin covers bonded to the front of the teeth to improve their shape and proportions, while crowns can rebuild a tooth that's worn or small. Neither removes gum, but both change how balanced your smile looks, and they're often paired with gum reshaping when a bigger change is the goal.

If It's Your Bite or Tooth Position: Invisalign or Braces

When a gummy smile is tied to how your teeth are positioned or how your bite comes together, moving the teeth can help. Invisalign clear aligners or braces gradually shift your teeth into a better position, which can reduce how much gum shows over time. It's a slower route, but it works on the underlying alignment rather than just the appearance, and it can improve your bite along the way.

If Your Lip Lifts Too High: A Referral Option

For some people, the gums and teeth are fine, and it's simply an upper lip that travels higher than average when they smile. This can sometimes be softened with muscle-relaxant injections that limit how far the lip rises, given by a suitably qualified practitioner. The effect is temporary and wears off over time. It isn't something every dental practice provides, so your dentist may talk it through with you or refer you on if it turns out to be the right fit for your smile.

If Teeth Haven't Fully Come Through: Crown Lengthening

Occasionally teeth stay partly covered by gum, and sometimes a little bone, because they never fully erupted. Crown lengthening is a minor procedure that reshapes the gum, and if needed, a small amount of bone, to uncover more of the tooth. It's more involved than simple gum reshaping and is planned carefully with your dentist, sometimes alongside a referral.

How We Approach Gummy Smiles at Henley Dental

At Henley Dental in Homebush West, we start every gummy smile by working out what's actually causing it, rather than jumping straight to a treatment. From there, we'll talk you through the options that suit your situation and what you'd like to change. Our cosmetic dentistry and smile makeover options bring together treatments like veneers, crowns and Invisalign where they'll genuinely help.

Results vary from person to person, which is exactly why we plan around your smile instead of a template.

What Happens at a Gummy Smile Consultation

If you're weighing up gummy smile treatment in Homebush West, the first step is a consultation. Your dentist will look at your gums, teeth and bite, and how your lip moves when you smile, then talk through what's realistic for you. You'll leave with a clear idea of which option, or combination of options, makes sense, what each involves, and what it's likely to cost, before you commit to anything.

Frequently Asked Questions

Is gum reshaping painful? 

It's usually done under local anaesthetic, so you shouldn't feel the procedure itself. Some mild tenderness afterwards is normal and tends to settle within a few days.

Does the gum grow back after reshaping? 

When reshaping is done for cosmetic reasons on healthy gums, the new gumline is generally stable. Your dentist will explain what to expect for your particular case.

Can Invisalign fix a gummy smile? 

It can help when the cause is the position of your teeth or your bite. It won't suit every gummy smile, which is why the cause is assessed first.

How much does gummy smile treatment cost? 

It depends on the cause and the treatment involved, so there's no single figure. You'll get a clear quote at your consultation once your dentist knows what's needed.

Is a gummy smile bad for my health? 

In most cases, it's purely cosmetic and not a health problem. It's still worth having your gums checked, so you know everything underneath is healthy.

A gummy smile is common, and in most cases it's very treatable once you understand what's behind it. Whether that turns out to be gum reshaping, veneers, Invisalign or a mix of a few things, the key is matching the treatment to the cause rather than guessing.
