Manual Lymphatic Drainage After Wisdom Tooth Removal: What a 2025 Study Found

Swelling, discomfort and restricted movement are common concerns following many surgical procedures. Although these symptoms are often a normal part of healing, they can make the first several days of recovery more uncomfortable.

A 2025 randomized clinical trial published in BMC Oral Health examined whether Manual Lymphatic Drainage, also called MLD, could help reduce swelling, pain and restricted mouth opening after impacted wisdom tooth surgery.

The researchers found that recovery periods that included Vodder Manual Lymphatic Drainage had significantly less postoperative swelling, lower reported pain and better mouth opening than recovery periods that included routine postoperative care alone.

While this study focused specifically on wisdom tooth removal, it adds to the growing research surrounding gentle lymphatic techniques during postoperative recovery.

What Is Manual Lymphatic Drainage?

Manual Lymphatic Drainage is a specialized hands-on technique that uses gentle, rhythmic and precisely directed movements.

Unlike deep-tissue massage or forceful bodywork, traditional MLD uses very light pressure. The goal is to work with superficial lymphatic pathways located close to the skin rather than pressing deeply into muscles.

The technique used in this study was based on the Vodder method of Manual Lymphatic Drainage. The researchers described the treatment as gentle, rhythmic and painless, beginning near the supraclavicular area before progressing toward the surgical region.

This distinction is important because not every service marketed as “lymphatic massage” follows the same methods, pressure or clinical reasoning.

Why Does Swelling Develop After Surgery?

Surgery creates a controlled injury to the body. In response, the immune system sends fluid, proteins and inflammatory substances into the affected tissues to support healing.

This process can result in:

• Localized swelling

• Tightness or pressure

• Tenderness

• Reduced movement

• Temporary discomfort

  
  

Following lower wisdom tooth surgery, swelling frequently increases during the first few days. Pain and jaw restriction, sometimes called trismus, may occur at the same time. The study authors noted that facial swelling commonly peaks within approximately 72 hours and then gradually decreases over the following days.

Manual Lymphatic Drainage is designed to support superficial fluid movement without using aggressive pressure on healing tissues.

How Was the Wisdom Tooth Study Conducted?

The clinical trial included 46 healthy patients between 18 and 26 years old. Each participant had two similar, symmetrically impacted lower wisdom teeth that required removal.

This was a split-mouth randomized clinical trial.

That does not mean researchers simply treated one side of the face while both sides healed simultaneously. Each patient underwent two separate wisdom tooth surgeries, spaced two weeks apart.

After one surgical procedure, the recovery plan included routine postoperative care and medication.

After the other surgical procedure, the patient received the same routine postoperative care plus Manual Lymphatic Drainage.

This allowed the researchers to compare two recovery periods within the same individual, helping reduce differences that might otherwise occur when comparing unrelated groups of patients. The outcome evaluators were not told which surgical side had been assigned to MLD.

What Did the MLD Treatment Include?

The Manual Lymphatic Drainage sessions were performed by a professional physiotherapist using the Vodder technique.

The first session took place during the afternoon following the morning surgery. Treatment continued over the first three postoperative days.

The study describes the sequence as beginning near the supraclavicular lymphatic region before gradually progressing toward the surgical area using techniques such as:

• Stationary circles

• Gentle pumping movements

• Circular strokes

• Carefully directed pushing movements

  
  

The treatment was intended to encourage fluid movement away from the swollen surgical region through the head and neck lymphatic pathways.

How Did Researchers Measure the Results?

One strength of this study was the way facial swelling was evaluated.

Rather than relying only on photographs, visual observation or a tape measure, researchers used the 3dMD FACE System to create three-dimensional facial images and calculate changes in facial volume.

Swelling measurements were recorded before surgery and again on the third and seventh postoperative days.

The researchers also measured:

• Pain using a Visual Analog Scale

• Maximum mouth opening using a digital caliper

• Jaw restriction during the first week of recovery

  
  

These measurements allowed the research team to evaluate changes in swelling, discomfort and function.

What Did the Study Find?

The recovery periods that included Manual Lymphatic Drainage showed significantly better results than those involving routine care alone.

Less facial swelling

The MLD condition produced less postoperative edema during the first three days. Researchers also observed faster reduction of existing swelling by the seventh postoperative day.

Lower reported pain

Average pain scores recorded on postoperative days one, two, three and seven were significantly lower following the surgery that included MLD.

Better mouth opening

Participants had better maximum mouth opening on both the third and seventh postoperative days after receiving MLD. This suggests less restriction from swelling, pain and protective muscle tension.

Overall, the researchers concluded that Manual Lymphatic Drainage may be a useful method for reducing swelling, pain and trismus after impacted lower wisdom tooth removal.

What Are the Study’s Limitations?

The findings are encouraging, but they should be interpreted carefully.

This was one relatively small clinical trial involving 46 participants. The patients were young, generally healthy adults between 18 and 26 years old who were having a very specific oral surgery.

The study did not evaluate:

• Cosmetic surgery

• Abdominal surgery

• Joint replacement

• Cancer-related surgery

• Patients with complex medical conditions

• Patients experiencing infection or other surgical complications

  
  

The researchers also acknowledged that patient perception and a possible placebo effect could have influenced some outcomes, particularly reported pain. They recommended additional controlled studies comparing MLD with other postoperative interventions.

The study was also registered retrospectively rather than before participant enrollment, which is worth considering when reviewing its strength.

For these reasons, the results should not be interpreted to mean that lymphatic massage is appropriate after every surgery or that it can replace medical treatment.

What Does This Research Mean for Other Types of Surgery?

This study cannot prove that Manual Lymphatic Drainage will produce identical results after cosmetic surgery, orthopedic surgery, abdominal procedures or other operations.

However, it provides clinically relevant evidence that a gentle, professionally administered Vodder MLD protocol may influence several common postoperative concerns:

• Swelling

• Pain

• Tissue pressure

• Restricted movement

• General recovery comfort

  
  

It also reinforces that postoperative lymphatic work should be gentle and intentionally timed.

More pressure is not necessarily more effective. Deep, forceful or painful massage is not the same as traditional Manual Lymphatic Drainage and may be inappropriate during early healing.

The exact treatment plan should depend on the procedure, healing stage, medical history and instructions provided by the surgeon or medical team.

Is Lymphatic Drainage Safe Immediately After Surgery?

Not every patient should receive lymphatic massage immediately after a procedure.

Before treatment, a qualified practitioner should consider factors such as:

• The type and date of surgery

• The surgeon’s instructions

• Incision condition

• Drain placement

• Current medications

• Infection risk

• Blood-clot risk

• Cardiac or kidney conditions

• Unexpected pain or swelling

• Other postoperative complications

  
  

Massage should never be used to delay medical evaluation.

Possible warning signs such as fever, increasing redness, warmth, drainage, sudden one-sided swelling, shortness of breath, chest pain, severe pain or rapidly worsening symptoms should be reported to the appropriate medical provider.

A lymphatic practitioner does not diagnose surgical complications or replace the surgeon’s follow-up care.

The Takeaway

A 2025 randomized clinical trial found that adding three sessions of Vodder Manual Lymphatic Drainage after impacted wisdom tooth surgery was associated with:

• Less postoperative facial swelling

• Lower pain scores

• Better mouth opening

• Less jaw restriction during recovery

  
  

The study does not prove that MLD is appropriate for every person or every operation. Still, it adds meaningful evidence to the conversation around gentle lymphatic care and postoperative swelling.

When performed at the right time, with the appropriate technique and in coordination with medical guidance, Manual Lymphatic Drainage may be a helpful component of a broader postoperative recovery plan.
