Dental Bone Graft: Process, Purpose & Healing Stages

What is a Dental Bone Graft?

Before looking at what dental conditions may lead to a bone graft, we first need to answer the question ‘what is a dental bone graft?’.

A dental bone graft is a common oral surgery which aims to support a weakened or diminished jawbone. There are several variations of dental bone grafts, but in each procedure, a bone material is attached to the jawbone to reinforce it.

Bone grafts provide a framework from which your body’s bone tissue can grow and regenerate, reinforcing and strengthening your jaw.

In most cases, one of the following four materials will be used for your dental bone graft:

• Xenografts: Bone taken from animals, typically cows or pigs

• Alloplasts: Bone-like material made from synthetic materials, including calcium phosphate and calcium sodium phosphosilicate

• Allografts: Bone taken from your own body

• Autografts: Bone taken from another person, typically a cadaver donor

Though allografts are the preferred material for most dental bone grafts, research is inconclusive as to what the ideal material for a bone graft is.

What Conditions Require a Dental Bone Graft?

Dental bone grafts can help treat several oral conditions, including:

• Tooth Implants

Dental implants are used to replace extracted teeth. They are screwed into the jawbone and provide a secure foundation for a dental crown.

In some cases, bone grafting for dental implants may be necessary as the jawbone needs to be solid and secure to hold the implant effectively.

• Gum Disease

Dental bone grafts can function as gum disease treatment if the condition is serious.

In cases of moderate and advanced periodontitis, bacteria can erode parts of the jawbone that hold the teeth in place. Alongside dental curettage, a bone graft can restore damaged bone and prevent further complications and infections that may come from gum disease.

• Bone Loss

As well as being part of gum disease symptoms, jawbone loss can happen for a variety of reasons, including bone thinning due to age and oral trauma.

Bone loss in the jaw can affect your appearance and oral health, so it is important to perform a bone graft to reduce the risk of any complications.

Other reasons for a dental bone graft include:

• Loose, unstable teeth

• Denture fitting

• Widening the jawbone for cosmetic reasons

Dental Bone Graft Procedure

The exact dental bone graft procedure can vary depending on where in the mouth it takes place, but some steps are common across surgeries. The three main types of dental bone graft are:

• Block Bone Graft: Bone is taken from the back of the mouth and used to fix bone loss at the front of the jaw/mouth

• Sinus Lift: A bone material is used to restore loss that has happened around the upper molars and stop the sinuses from moving down

• Socket Graft: Performed in conjunction with a tooth extraction to stop potential bone loss

Here is an example of what dental bone graft procedure may happen:

1. Depending on patient preference, a dentist will begin by either numbing your gums with a local anaesthetic or administering a general anaesthetic for sedation.

2. Next, the affected area is cleaned, and an incision is made in the gums to separate them from the jawbone.

3. The chosen grafting material is then placed in the area of bone loss and secured with a protective membrane. These membranes may be absorbed into the skin during the healing process or may require another dental procedure to remove.

4. The incision is closed with stitches, and the oral surgery is finished.

Is a Dental Bone Graft Painful?

A bone graft can be a relatively simple procedure, particularly if it does not involve using bone from your own body. Thanks to anaesthesia, you should not feel any pain during your dental bone graft, but it is normal to feel a throbbing pain after bone grafts.

Any discomfort should be light enough to be eased by over-the-counter pain medication, but your dentist may prescribe stronger pain medication if the surgery is more invasive. Discomfort and throbbing pain after bone grafts should not last more than a few weeks.

Recovering from a Bone Graft

Recovering from a dental bone graft can take anywhere from three to twelve months, depending on the size of the graft. Symptoms and side effects of the procedure should disappear over time, with the most uncomfortable period being the initial week of healing.

In the week following oral surgery, you will most likely experience bloody and swollen gums, pain around the site of surgery, and the formation of a blood clot at the site of the incision. To manage this, your dentist may prescribe pain medication and antibiotics to ensure that the wound does not become infected.

After a week or so, the pain should subside as the site of the wound heals over. In the next three to twelve months (depending on the size of the graft), the following dental bone graft healing stages will take place:

• Tissue Regeneration: The body begins to form bone cells and blood vessels within the graft material

• Bone Growth: Using the graft as a scaffold, the body forms new bone tissue, which begins to replace graft material

• Bone Solidification: The bone tissue solidifies, reinforcing the jaw and readying the mouth for everyday life or any oral surgeries which may need to follow

If you experience a fever, pus drainage, or excess swelling during any stage of the healing process for a dental bone graft, make sure to contact your dentist, as it could be a sign of infection.

What Can Influence Healing Time for a Dental Bone Graft?

The size of the graft is not the only factor that can influence the healing time for a dental bone graft. The following factors can affect healing:

• Graft Material: The material used for your dental bone graft will affect how long it takes to heal, with each variant integrating at a different rate.

• Underlying Health Conditions: Certain health conditions, including diabetes and autoimmune disorders, can affect the rate at which a bone graft integrates and heals.

• Oral Hygiene: Taking care to maintain good oral hygiene and follow advice given by your dentist following oral surgery minimises the risk of infection and gives the body the best environment to heal in.

• Nutrition: Post-dental bone graft, your dentist may recommend a soft diet or avoiding certain foods. This will allow the site of surgery to heal without being disrupted by irritants.

• Surgery: The size, length, and techniques deployed in your oral surgery will all have an impact on the length of time that the procedure takes to heal.

If you are wondering how to speed up bone graft healing, then you may be disappointed. The body takes time to heal properly, and while good hygiene and following your dentist’s recommendations give it the best conditions to heal in, they will not speed up healing.

Maximise Your Dental Health with Oral-B

Good oral care is always important, but especially following an oral surgery procedure. After a dental bone graft, a careful and consistent oral care routine is essential to protect the healing site and prevent complications. Immediately following surgery, you should follow your doctor’s instructions for your oral care routine. Once healed, continued oral care is important to maintain oral health. That’s where Oral-B comes in.

The Oral-B iO Series electric toothbrushes are designed to provide a gentle yet highly effective clean, combining micro-vibrations with a smart pressure sensor to help you brush safely and thoroughly. The iO Series makes it easy to care for your mouth without risking overbrushing or irritating sensitive areas.

Oral-B advocates the importance of maintaining strong oral hygiene habits, which includes regular trips to the dentist or dental hygienist —especially following oral surgery. By using the right tools and staying proactive with your dental care, you’re giving your smile the best chance at a smooth recovery and long-term strength.
