Why replace missing teeth? Effects and options

Losing a tooth to decay, gum disease or an injury is common, and many people wonder whether the gap really needs to be filled. So why replace missing teeth? A gap can affect the bone, the neighbouring and opposing teeth, chewing, speech and confidence. This guide explains, in general terms, what can happen after tooth loss, when replacement is usually advised and the main options available in Chandigarh.

Effects of missing teeth: what happens if a gap is left

The changes after tooth loss usually happen slowly, which is why they are easy to overlook. They depend on which tooth is missing, how many teeth are missing and your bite.

The bone where the tooth was can shrink

The bone that held a tooth's root is maintained partly by the tooth itself. After an extraction, the socket fills with new bone, but the ridge also becomes narrower and lower. A 12-month study of single premolar and molar extractions found that the ridge became markedly narrower, with about two-thirds of that loss of width in the first three months (Schropp and colleagues, 2003). The amount differs from person to person. Read more about how dental implants may help limit bone loss and about bone loss treatment at ADC.

Neighbouring teeth can tilt and drift

The teeth next to a gap no longer have a neighbour to lean against, so over time they can tilt or drift into the space. This can open small gaps elsewhere, trap food and make the teeth harder to clean.

The opposing tooth can over-erupt

A tooth with nothing to bite against in the opposite jaw can slowly move further out of its socket towards the gap. Over-eruption can change the bite and, later, make replacement more complicated.

Chewing and the bite can change

With fewer teeth, chewing forces fall on the teeth that remain. Some people start to chew on one side only. Missing back teeth can reduce chewing ability, and changes in the bite can add wear to the remaining teeth.

Appearance and speech

A missing front tooth is visible when you smile and can affect certain sounds. When many teeth are lost, the lips and cheeks lose some of their support, which can change the shape of the lower face.

Confidence and quality of life

A systematic review found that tooth loss is associated with poorer oral health-related quality of life, and that the number and position of missing teeth affect how much it matters, with front teeth often having the greatest impact (Gerritsen and colleagues, 2010).

Does every missing tooth need to be replaced?

Not always. Whether a gap should be filled depends on the tooth, your bite and your wishes. For example, a missing molar at the very back may not need replacing if the bite is stable and chewing is comfortable. A review of the 'shortened dental arch', where the front teeth and premolars are kept but some molars are missing, found that many people chew comfortably with that pattern (Kanno and Carlsson, 2006). It does not apply to every gap. A missing front tooth, or a gap with teeth on both sides, is more often replaced.

If you decide to leave a gap, regular check-ups let your dentist watch for drifting, over-eruption and bite changes.

When should a missing tooth be replaced?

There is no single right time, but planning early keeps more options open. If a tooth has to be removed, your dentist can often plan the replacement before the extraction. For an implant, placement may be at the same visit as the extraction, a few weeks later, or after the site has healed for some months, depending on the bone, the gum and any infection. Read more in dental implant after tooth extraction: immediate or delayed placement and about tooth extraction at ADC.

If keeping the width of the ridge matters for a later implant, a bone graft may be placed in the socket at the time of extraction; whether you need one depends on the site and the plan. See what to expect with bone grafting.

Options to replace missing teeth

Each option has advantages and limitations. The main choices are:

Dental implant with a crown. An implant is placed in the jawbone and, after healing, a crown is fitted on it. The neighbouring teeth are not reshaped (ADA MouthHealthy). See dental implants in Chandigarh and our complete guide to dental implants.
Implant-supported bridge. When several teeth in a row are missing, two or more implants can support a fixed bridge. Read about implant-supported teeth and bridges.
Tooth-supported bridge. In a conventional bridge, a false tooth is held by crowns on the neighbouring teeth, so those teeth are reshaped. Bridges can be made of metal-ceramic (PFM), zirconia or E-max; the material depends on the tooth, the length of the bridge and the bite. A tooth-supported bridge does not stop the bone shrinking under the false tooth (Cleveland Clinic). See dental crowns and bridges and how dental bridges restore smiles.
Removable partial denture. The false teeth sit on a gum-coloured base, sometimes with a metal framework. The denture usually clips to the remaining teeth and is taken out for cleaning (NHS). See dentures in Chandigarh.
Complete denture or implant-supported denture. When all the teeth in a jaw are missing, a complete denture can replace them, and implants can be used to hold a denture more securely or to support fixed teeth. See implant-supported dentures and dentures vs implants: how to choose.

How the right option is chosen

Your dentist will consider your general health, the amount of bone, the health of the gums and neighbouring teeth, your bite, how easy each option is to clean, the number of visits, the cost and your own preference. Our tooth replacement page gives an overview of the treatments ADC offers.

Looking after the teeth you still have

Whatever you decide, the teeth that remain are worth protecting. Brush twice a day with fluoride toothpaste, clean between your teeth, keep up regular check-ups and have gum disease treated early, as it is a common cause of tooth loss in adults.

The clinic is in Sector 21, Chandigarh, within easy reach of Mohali, Panchkula and Zirakpur.

Frequently asked questions

Is it bad to leave a gap after losing a tooth?
Not always, but a gap can lead to bone shrinkage, drifting or tilting of the neighbouring teeth and over-eruption of the opposing tooth. Your dentist can advise whether replacing it is worthwhile for you.

How soon after an extraction can a tooth be replaced?
It depends on the option and the site. An implant may be placed at the same visit as the extraction, or weeks or months later. Bridges and dentures are usually made once the gum has settled, and a temporary option can often be provided in the meantime.

Which tooth replacement option lasts the longest?
There is no single answer. How long any replacement lasts depends on your gums, your bite, your general health and how well it is cleaned and maintained. All options need regular check-ups.

Can I have an implant if the bone has already shrunk?
It may still be possible. It depends on how much bone is left, where the gap is and your general health; bone grafting or another technique may be needed first. Read about dental implants with bone loss.

How much does it cost to replace a missing tooth?
The cost depends on the option and the number of teeth, and is explained in your written estimate after the consultation. Instalment and financing options are available; ask our team for details.
