Full arch dental implants (All-on-4® dental implants) don’t have a separate cleaning routine like dentures, but replacement teeth still need proper daily care, just like natural teeth. Read this guide to find out what you need to know about maintaining your All-on-4® teeth after they’re first fitted and in the long term.

Why is oral hygiene important?

Dental biofilm (bacteria)
Plaque and bacteria can form on and around your replacement teeth, just as it can build up on natural teeth and gums. Maintaining a good oral hygiene routine helps to reduce plaque, which can lead to staining and discolouration of a bridge, bad breath, and if left untreated, it can cause more serious problems, such as peri-implant disease (a form of gum disease affecting dental implants).
If gum disease develops, it may cause gums to pull back where the implant is held in place, leading to implant failure. Gum disease is also linked with health risks elsewhere in the body, including an increased risk of heart problems, stroke and diabetes, among others.
Mouth rinsing and teeth cleaning after full arch implant surgery

The day after your dental implants are placed, it’s important to rinse your mouth gently using a warm saltwater wash. Saltwater rinses should be done two to three times a day, especially after eating.
To prepare a saltwater rinse, we recommend:
- Mix one teaspoon of salt into a glass of warm water
- Take a mouthful and hold it over the surgical site
If you have been prescribed a Chlorhexidine mouthwash by your dentist, it should be used twice a day – ideally first thing in the morning and before you go to bed at night.
To use the mouthwash, we recommend:
- Hold a small amount of the mouthwash in your mouth, taking care not to swallow
- Gently move your head from side to side so the mouthwash reaches all parts of your mouth
- Keep the mouthwash in your mouth for 30–60 seconds, then spit it out
Chlorhexidine mouth rinses should only be used for one to two weeks. Using them for longer than two weeks may cause staining of your new bridge. After this time, you can continue with salt water rinses.
Looking after your oral hygiene in the long term
Our dentists at Perth Dental Implant Centre will give you personalised advice about caring for your new teeth and your oral health, based on your individual needs. Here’s some general guidance.
Toothbrushing

You will be provided with a soft-bristled toothbrush to use for the first two weeks. This brush can be used to brush all surfaces of your A=full arch dental implant bridge, including the area where the bridge meets the gums. You will need to take care brushing the gums for the first two weeks while they heal.
After two weeks this area can be brushed more thoroughly and you may consider switching to an electric toothbrush to help remove food and plaque from hard-to-reach areas.
WaterPik® and Flossing
You will be provided with a Waterpik® water flosser to use two weeks after surgery (unless you have had zygomatic implants placed, in which case you will need to wait 6 months before using a water flosser). The water flosser should be used twice a day to remove plaque and food debris from under the bridge. After a few weeks when the gums have fully healed you can also use other cleaning aids such as Piksters®, superfloss and X-floss to clean under the bridge and around dental implants.

Healthy diet

Unlike dentures, you don’t have to give up certain foods in the long term with full arch dental implants, but it’s still important to maintain a healthy diet and to limit sugar that feeds bacteria in plaque.
- For the first few days after implant surgery, we recommend a nutritious liquid diet (like broths, soups, smoothies and yoghurts).
- Once your bridge has been fitted, you can begin eating soft or pureed foods (such as mashed potato, scrambled eggs and soft fruits) for around 7 days.
- Hard, crunchy and sticky foods should be avoided until the implant site has completely healed, usually within 3 months of surgery.
In the first three days after surgery, we recommend avoiding hot drinks and do not use a straw. For more information on a healthy diet post implant surgery, read our guide to what to eat after dental implant surgery.
Lifestyle habits
Smoking should be completely avoided with dental implants, as it affects healing and increases your risk of infection and implant failure, among other health risks. Alcohol should be avoided for the first few days after implant surgery, or if you’re taking prescription medication.
Some habits, like chewing objects and teeth grinding, may damage your bridge over time, or lead to other oral health problems. If you grind your teeth, your dentist will recommend wearing a custom night guard to help protect your new bridge.
Pre-existing medical conditions
If you have an existing medical condition or are taking medication that may affect your suitability for All-on-4® implants or your healing period, this should be discussed with your doctor and our dentist so we can help you to lower your risk factors.
Regular check-up and cleans
As with natural teeth, regular dental check-ups and professional cleans are important for checking the condition of your implant bridge and your overall oral health. We recommend visiting your dentist every 6–12 months, depending on your individual needs. You dentist will professionally clean your bridge using an ultrasonic bath, stain removal tools and polish. We also recommend a dental x-ray every 1–2 years so we can check the health of the bone around your implants.
Full arch implant bridge repairs and replacement
Full arch implant bridges are hard-wearing and designed to last for many years, but they will need replacing eventually, whether due to normal wear and tear or accidental damage. It may also be possible to repair some damage to an custom-milled PMMA (acrylic) bridge by replacing individual teeth.
Bridge repairs
Our technicians can repair minor damage to an custom-milled PMMA (acrylic) bridge on the same day, or within 48 hours for larger repairs. The cost of repair to an custom-milled PMMA (acrylic) ranges from $350–$600. Zirconia bridge are more difficult to repair and may need to be replaced entirely.
Repairs resulting from mechanical failure are usually covered by a warranty.
- Custom-milled PMMA (acrylic) bridge warranty 12-months
- Zirconia bridge warranty 10-years
Bridge replacement

We offer two options for replacing a full arch implant bridge, depending on your needs and price range:
- Custom-milled PMMA (acrylic) bridge: $2,000 per arch or $3,500 for both
- Zirconia bridge: $10,500 per arch
