Teeth replacement options: What are the different options to replace missing teeth?

DesignIcon

Thinking about replacing your missing teeth? If so, you’re probably wondering about the different teeth replacements available. And the good news is that if you have lost teeth, you’re certainly not lost for options when it comes to restoring your smile.

Maybe you’re interested in a long-lasting fixed solution like dental implants. Or perhaps you’re considering the more cost-effective option of removable dentures. To help you make a more informed decision about the right teeth replacements for you, let’s explore the different options to replace missing teeth, as well as the pros and cons of each.

Dental implants

Dental implants are the closest teeth replacements to your natural teeth. This option is used for patients who want to replace a single missing tooth or several missing teeth in different parts of the jaw (i.e. not in a row). During the dental implant procedure, a patient will be put under twilight sedation so they remain calm and comfortable while a titanium implant post is surgically inserted into the jaw. This implant post acts as an artificial tooth root to provide stability and support for the implant tooth, which is connected on top. The titanium implant will fuse with the jaw bone in a process called osseointegration over a period of 3 to 6 months.

Pros of dental implants

Look and function like natural teeth
Durable
Fixed solution
Prevents jaw bone loss
Does not impact surrounding teeth

Cons of dental implants

Requires surgical procedure
Requires a lengthy recovery and healing time of up to 6 months
More expensive than removable teeth replacements
Only suitable for patients with enough bone density

All-on-4 dental implants

All-on-4 is the only fixed full-arch treatment backed by 25 years of clinical success. This teeth replacement option is designed for patients who are about to lose or have lost all or most of their teeth in their upper or lower jaw. The All on 4 procedure involves the placement of at least 4 (or up to 6) dental implants in the jaw, with two straight implants at the front and two angled implants at the back. The innovative implant placement used in the All on 4 treatment concept helps to utilise more bone density to support the tooth bridge and, in most cases, avoid the need for bone grafting. This means even patients with severe bone loss can potentially be good candidates for All-on-4 treatment. Once the implants are inserted, the tooth bridge can be connected in as little as 3 days after surgery.

The cost of All on 4 is higher than removable dentures, however, it is a far superior teeth replacement option in terms of durability, longevity, functionality and appearance. Plus, we offer flexible finance options and All-on-4 payment plans at our Gregory Hills or Moss Vale dental clinic so you can unlock the smile you deserve without the financial woes.

Pros of All-on-4

Replace all missing teeth with a fixed solution in as little as 3 days
Look, feel and function like real teeth
Durable with a longer lifespan than many other replacement teeth options
Rarely requires bone grafting and prevents bone loss by stimulating jaw bone
High success rate
Easy to clean

Cons of All-on-4 implants

Higher cost than removable dentures
Requires surgery
Requires a recovery and healing period
Small risk of complications (as with all surgical procedures)

Full mouth dental implants

This teeth replacement option is designed to replace all teeth in the upper or lower jaw, using up to 8 individual implants to secure a dental bridge in place. The implants are positioned straight (not angled) so this treatment is only suitable for those who have adequate jaw bone density or are able to have a bone graft.

Pros of full mouth dental implants

More secure alternative to denture
Stimulates jaw bone and prevents further bone loss
Looks and functions like natural teeth

Cons of full mouth dental implants

Most expensive option for replacing all missing teeth
May require several dental procedures over a number of months or years
Only suitable for patients with sufficient bone density

Implant-supported bridge

An implant-supported bridge offers a fixed solution for patients who want to replace several missing teeth in a row. It involves the placement of at least two dental implants in the jaw, at each end of the row of missing teeth. A tooth bridge of several teeth is then connected on top.

Pros of implant-supported bridge

Look, feel and function like natural teeth
Secure, fixed solution
Durable
Prevents jaw bone loss
No damage to surrounding teeth

Cons of implant-supported bridge

Requires surgery
Requires recovery and healing time of up to 6 months
May require existing teeth to be removed
More costly than partial dentures

Tooth-supported bridge

A tooth-supported bridge is ideal for those who want to replace several missing teeth in a row, but don’t want to undergo implant surgery or have insufficient jaw bone density to support dental implants. Instead of dental implants, this teeth replacement option uses the teeth on either side of the row of missing teeth to secure the dental bridge in place.

Pros of tooth-supported bridge

No surgery or recovery time required
Looks and functions like natural teeth
Less expensive than an implant-supported bridge

Cons of tooth-supported bridge

Supporting teeth may be at risk of damage
Existing teeth may need to be removed
Does not prevent jaw bone loss
Can be difficult to clean, especially if food gets caught underneath the tooth bridge

Overdentures (implant-supported overdentures)

This teeth replacement is only used for those who have lost all or most of their bottom teeth. It involves the placement of two dental implants in the bottom jaw to hold a removable denture in place. The denture is fitted with special attachments that ‘snap’ onto the implants (this is why they’re sometimes called ‘snap-on dentures’).

Overdentures involve the placement of two dental implants in the bottom jaw to hold a removable denture in place.

Pros of overdentures

Cost-effective in comparison to other teeth replacements
Implant-supported and more secure than traditional dentures

Cons of overdentures

More expensive than traditional removable dentures
Only suitable for teeth replacement in bottom jaw

Dentures

Dentures are one of the more affordable teeth replacement options. Patients may opt for a partial denture if they’re missing one or a few teeth, or full dentures if they’re missing all of their teeth. However, dentures only replace the teeth, not the roots, meaning they do not stimulate the jaw bone to prevent bone loss. This means that over time, denture wearers will suffer from jaw bone loss.

Pros of dentures

More cost-effective than other teeth replacement options
Quick and non-invasive treatment
Does not require surgery (unless existing teeth need to be removed)
No downtime or healing period
Low maintenance and easy to clean

Cons of dentures

Must be replaced every 5 to 10 years
Does not prevent and can worsen bone loss over time
Can be uncomfortable or painful at times
Can be loose and ill-fitting
May affect what you can/cannot eat (upper dentures also cover taste receptors on roof of mouth)

A combination treatment

For some patients, the most suitable teeth replacement option is a combination of treatments. This approach could involve single implants, dental crowns, tooth bridges or implant-supported bridges.

A dental crown is a tooth-shaped cap that fits snugly over your entire tooth. It’s sometimes recommended to strengthen a weak, cracked or worn-down tooth.

Pros of a combination treatment

Healthy, natural teeth can be saved

Cons of a combination treatment

Can be expensive
May involve a lengthy treatment time with multiple procedures

Do nothing

Some patients with missing teeth may be tempted to do nothing, thinking that this will save them money and reduce their risks of complications.

But beware — if you choose not to replace missing teeth, you could end up with bigger (and more costly) problems in future. Not only will this have a detrimental impact on the function and appearance of your teeth, but it can also lead to a number of physiological and psychological issues, such as:

Increased risk of damage and decay to remaining teeth
Jaw bone loss
Difficulty eating and speaking
Changes to facial bone structure and appearance
Low self-confidence
Social withdrawal
