Honest and detailed comparison between dental implants and removable dentures: advantages, disadvantages, costs and long-term quality of life.
The most frequently asked question in my practice
Among the most frequent questions I receive from new patients is undoubtedly: "Is it better to have an implant or a removable prosthesis?" The honest answer is that it depends on each specific case, but in the vast majority of situations, dental implants offer significantly superior quality of life compared to removable prostheses. Here I go through both options honestly and thoroughly.
Removable dentures: what you should know
Removable prostheses (commonly called dentures or plates) are appliances that replace lost teeth and that the patient can take out to clean. They can be complete (when no natural teeth remain) or partial (when some natural teeth remain and serve as support).
- Advantages: lower initial cost, fast process, no surgery required, adjustments can be made easily.
- Disadvantages: instability and movement while eating or speaking, progressive bone loss (bone that receives no chewing stimulus resorbs), the need for relining or replacement every 5 to 7 years, discomfort and social embarrassment for many patients, dietary restrictions (avoiding hard or sticky foods), more complex hygiene.
Dental implants: the definitive solution
- Advantages: chewing function comparable to natural teeth, preservation of the alveolar bone, superior and natural aesthetics, they are not removed (greater comfort and confidence), no dietary restrictions, long durability (they can last a lifetime), significantly improved self-esteem and quality of life.
- Disadvantages: higher initial financial investment, surgery required, a longer process (months rather than weeks), not every patient is an immediate candidate (bone grafts may be needed first).
The factor that changes the most: quality of life
In more than 17 years of clinical practice, I have seen firsthand the impact that moving from a removable denture to implants has on patients' quality of life. The difference is, in many cases, transformative. Patients who avoided eating in public, who felt embarrassed to laugh, who slept afraid their denture would shift, recover a freedom and confidence they had not felt in years.
When can a removable denture be the better option?
There are situations where a removable prosthesis is the most appropriate option: when the patient is not a medical candidate for surgery (because of severe uncontrolled systemic conditions), when available bone is insufficient and the patient does not want or cannot undergo bone grafting, as a transitional solution while an implant-supported rehabilitation is planned, or when the budget available at that moment does not allow for the implant option.
Frequently asked questions
▸What lasts longer, an implant or a removable denture?
A removable denture has to be relined or remade every few years, because the bone underneath keeps resorbing and the denture stops fitting. An osseointegrated implant has no expiry date. Watch out for a common confusion: the implant and the crown are not the same thing. The crown is a wear part and gets replaced without touching the implant inside the bone.
▸Why does my removable denture get looser over the years?
Because it does not stop bone loss, it accelerates it. With no root to stimulate the bone, it keeps resorbing underneath the denture, so the base it rests on changes shape. That is the real reason it moves while eating or speaking, and no amount of adhesive fixes it.
▸When is a removable denture the better option?
When medical conditions rule out surgery, when the patient chooses not to have an operation, or as a temporary solution while something definitive is planned. There is also a middle option almost nobody explains: the overdenture, which clips onto implants and can be removed for cleaning, but does not move while eating.
▸Can an implant get cavities like a natural tooth?
No. Implants do not get cavities, and that is the fact that changes the comparison the most, because decay is what makes people lose the most teeth. What can become inflamed are the tissues around the implant, so hygiene and check-ups remain just as necessary.
▸How much does an implant cost compared to a removable denture?
The denture costs less on day one and more over time, because it has to be relined and remade. The implant concentrates the cost up front and then only needs check-ups. Every case is quoted after the 3D scan and the radiographs, never by eye, because the number of implants and the prosthetic material change the figure entirely.
