According to the Australian Institute of Health and Welfare (AIHW), Australian adults aged 15 and over are missing an average of 5.7 teeth, and this number increases with age. So, if you’re living with a gap right now, you’re not alone. In fact, one of the most common questions our dentists at Parkmore Family Dental hear is: does a missing tooth really need replacing?
Many people don’t realise that a gap isn’t a “set and forget” situation. Even when it doesn’t hurt, the space quietly keeps changing in the background. Rather than listing every possible problem, this guide explains what we see happen over time and the replacement options available at our clinic, so you can decide with confidence.
Is It Okay Not to Replace a Missing Tooth?
Sometimes, yes. Not every gap needs filling. Wisdom teeth, for example, rarely need replacing once removed, because most people chew comfortably without them. The same can apply to a missing back molar, as long as your bite stays stable. For most other teeth, though, a gap can gradually affect your surrounding teeth, your bite and your jawbone.
The right answer depends on which tooth is missing, the health of your remaining teeth and your personal goals. Rather than guessing, we as dentists recommend booking an assessment. We will examine the gap and take digital X-rays to check your bone and neighbouring teeth before talking you through whether replacement makes sense for you.
What Happens Over Time When You Don’t Replace a Missing Tooth?
In the First Few Months: The Jawbone Begins to Shrink
Every time you chew, your teeth stimulate the jawbone and help keep it strong. Without a tooth there, that spot no longer gets the same stimulation, so the bone slowly starts to shrink.
This can happen faster than you might think. A study found that the bone around a single-tooth extraction site became about 50% narrower over 12 months, with most of the change occurring in the first three months. This is why we encourage you to talk to us soon after a tooth is lost or removed.
Within the First Year or Two: Neighbouring Teeth Begin to Move
Teeth rely on each other for support. Once a gap opens up, the teeth on either side can slowly tilt or drift into the space. The tooth directly above or below the gap may also start to grow further out of its socket, because there’s no opposite tooth to bite against.
Do Teeth Shift After a Tooth Is Removed?
They can, but how quickly it happens varies from person to person. Some people notice movement within months; for others, it may take years. Once teeth have shifted, filling the gap becomes more complicated and may require orthodontic treatment first. If that’s the case for you, don’t worry. We can discuss options such as clear aligners to help guide teeth back into position before the gap is filled.
Over Several Years: Your Bite Begins to Shift
As teeth tilt and move, the way your upper and lower teeth meet can change. This may lead to:
- Uneven chewing: You might start favouring one side of your mouth without even realising it.
- Hard-to-clean pockets: As teeth lean out of line, they can leave narrow spaces that catch food after every meal.
- More decay and gum problems: Trapped food and plaque put the teeth next to the gap at greater risk.
- Jaw discomfort: Some people notice it as their jaw muscles adjust to a changed bite.
Regular check-ups and cleanings help us monitor these changes and spot early signs of tooth decay or gum disease near the gap.
In the Long Term: Your Face and Smile Begin to Change
With several teeth gone, the shrinking bone may no longer support your lips and cheeks the way it used to. Over time, this can make the lower face look slightly sunken.
When the gap is near the front, it can also affect your speech and leave you feeling self-conscious about your smile. If that sounds familiar, it’s worth knowing there are options, and we are happy to talk them through with you.
How Long Can You Wait to Replace a Missing Tooth?
There’s no set timeframe, but we encourage you to visit us soon after losing a tooth. Since most bone changes happen in the first few months, an early visit helps us assess your needs and discuss available treatment options.
If you’ve had a gap for years, please don’t let that stop you from getting it checked. We will assess your bone and surrounding teeth and explain what’s possible for you now. And if you’ve lost or damaged a tooth due to an injury, our guide on how dentists treat a broken or damaged tooth explains what to do straight away.
What Are the Options for Replacing a Missing Tooth?
At Parkmore Family Dental, we offer three main options for replacing a missing tooth, each with its own benefits, limitations and risks. The right choice depends on your oral health, medical history and budget. We will explain each suitable option, including costs, before you decide.
Dental Implants
A dental implant is a small titanium post fitted into the jawbone to hold a replacement tooth in place. Like a natural tooth root, it transfers chewing forces to the bone, which may help reduce bone loss in the area. The procedure involves minor surgery and requires enough healthy bone to support the implant. If the jawbone isn’t strong or thick enough, you may need a bone graft before the implant can be placed.
Our principal dentist, Dr Vicky Thai, has completed further training in implant dentistry through the Australian Society of Implant Dentistry. Learn more about dental implants at Parkmore.
Dental Bridges
A dental bridge replaces a missing tooth by securing an artificial tooth to the natural teeth beside the gap. While surgery isn’t usually needed, the neighbouring teeth often need to be reshaped to support the bridge. We match the bridge’s colour and shape as closely as possible to your natural teeth
Dentures
A partial denture is a removable plate that fills one or more gaps and can be taken out for easy cleaning. Dentures are often a more affordable starting point, although they may take some time to get used to. We provide full and partial dentures, and eligible concession card holders may be able to access dentures through the Victorian Denture Scheme.
Don’t Let Today’s Gap Become Tomorrow’s Treatment Plan
A gap may seem minor today, but the changes it triggers build up slowly over time. Understanding them gives you the chance to act before a simpler fix becomes a more complicated one.
