When is all-on-four teeth NOT a good option for me?

All-on-four teeth is not always your best solution to fixing your teeth. Sometimes its better to save your own teeth or go for dentures or full mouth dental implants. This all depends on many different factors. Here are some cases where going for all-on-4 teeth may not be your best solution:

(1) You still have plenty of healthy teeth left

Generally, if you have 6 or more healthy teeth in one arch, then all-on-four teeth is not advisable. Now by saying “healthy teeth” we mean that your remaining teeth don’t suffer from advanced gum disease or extensive tooth decay. Of course, if these teeth are loose or severely decayed, then all-on-4 is the best way to go. Similarly, if you only have 1 or 2 healthy teeth left within each arch, then you have to sacrifice these teeth to receive all-on-four teeth. However, if you have 6 or more healthy teeth within an arch, you should consider adding individual dental implants instead of going for all-on-4 teeth. Not only will this cost less, but it is easier and gives you better taste, function and proprioception.

(2) You want you’re teeth exactly as they were before you lost them

Plus, the teeth contain pink gum tissue which shows when your lips are retracted. If you want your dental implants to look identical to your actual teeth, then you have to go for full mouth implants instead.

(3) You’re happy with dentures

Believe it or not, not every denture wearer dislikes their dentures. In fact, some denture wearers do very well with their dentures and don’t mind wearing them. They talk, eat and function as if they had all of their own teeth and you wouldn’t know unless you asked them. For these individuals, investing in all-on-four teeth is not necessary.

(4) You can’t afford all-on-4 teeth

At $15,000 to $25,000+ per arch, all-on-four teeth are not inexpensive. If you can’t afford permanent teeth, consider implant-denture hybrid options instead. By placing just a few dental implants, you can stabilize your dentures without having to spend a fortune.
