What is the best treatment for mouth sores after dental implant placement?

Treatment of Mouth Sores After Dental Implant Placement

The best treatment for mouth sores after dental implant placement is a nonsurgical approach combining proper oral hygiene with mechanical debridement, pain management using topical anesthetics, and close monitoring to distinguish between simple peri-implant mucositis (reversible soft tissue inflammation) and more serious peri-implantitis (bone loss). 1

Initial Assessment and Diagnosis

First, determine whether you are dealing with peri-implant mucositis or peri-implantitis:

• Peri-implant mucositis presents as reversible inflammation of the peri-implant soft tissue without bone loss 1
• Peri-implantitis involves inflammation plus destruction of both soft and hard tissues surrounding the implant 1
• Bleeding on probing is the key clinical measure to distinguish between peri-implant health and disease 2

The prevalence of peri-implant mucositis is approximately 43%, while peri-implantitis affects about 22% of implants, making these complications common enough to warrant aggressive early management 2.

Primary Treatment Approach: Nonsurgical Management

The main therapy for mucositis and peri-implantitis is the nonsurgical approach, which includes manual treatment, drug therapy, laser therapy, and photodynamic therapy 1. This approach has been shown to be sufficient to improve beneficial systemic effects in patients 1.

Mechanical Debridement and Oral Hygiene

• Professional mechanical plaque removal combined with oral hygiene instructions has been shown to reduce clinical signs of inflammation 2
• Patient-administered mechanical plaque control with manual or powered toothbrushes is an effective preventive measure 2
• Microbial biofilm is the key factor in the development of peri-implantitis, making its removal the cornerstone of treatment 1

Pain Management

For pain control, use topical anesthetics as first-line therapy:

• Viscous lidocaine 2% can be applied as an anesthetic mouthwash to treat pain from stomatitis 1
• Coating agents may be used in conjunction with topical anesthetics 1
• For moderate pain, consider topical NSAIDs such as amlexanox 5% oral paste 1
• If mouthwash is painful, advise patients to use anesthetic agents beforehand 1

Antiseptic Rinses

• Antiseptic oral rinses such as 0.2% chlorhexidine digluconate or 1.5% hydrogen peroxide can be used twice daily to reduce bacterial colonization 3
• Increase frequency of antiseptic mouthwash up to each hour if necessary to treat active stomatitis 1

Advanced Treatment for Persistent or Severe Cases

Topical Corticosteroids

If ulcers develop or inflammation persists despite initial treatment:

• Dexamethasone mouth rinse (0.1 mg/ml) should be considered first when several locations of the oral cavity are involved or ulcerations are difficult to reach 1
• Clobetasol gel or ointment (0.05%) for limited locations and easy-to-approach ulcers 1
• Betamethasone sodium phosphate can be used as a rinse-and-spit solution 1-4 times daily for severe cases 3, 4

Escalation for Non-Responsive Cases

• If ulcers do not resolve, consider intralesional steroid injection (triamcinolone weekly; total dose 28 mg) in conjunction with topical clobetasol 1
• For highly symptomatic or recurrent ulcers, systemic corticosteroids (high-dose pulse 30-60 mg or 1 mg/kg oral prednisone/prednisolone for 1 week followed by dose tapering) should be considered 1

Supportive Care Measures

• Apply white soft paraffin ointment to the lips every 2 hours to prevent cracking and provide a protective barrier 3, 4
• Daily warm saline mouthwashes to reduce bacterial colonization and promote healing 3
• Mucoprotectant mouthwashes such as Gelclair can be used three times daily to protect ulcerated surfaces 3

Treatment of Secondary Infections

Monitor for and treat candidal infections:

• If candidal infection develops (particularly in patients on corticosteroid therapy), treat with nystatin oral suspension or miconazole oral gel 3, 4
• This is the most common side effect of topical steroid use in the mouth 4

Critical Pitfalls to Avoid

• Do not rely solely on adjunctive measures (antiseptics, local and systemic antibiotics, air-abrasive devices) as they have not been shown to improve the efficacy of professionally administered plaque removal in reducing clinical signs of inflammation 2
• Lack of regular supportive therapy in patients with peri-implant mucositis is associated with increased risk for onset of peri-implantitis 2
• Do not ignore bleeding on probing, as this is the key indicator distinguishing health from disease 2
• Postoperative infections after implant placement occur in 4-10% of patients and are important because applied treatments are often ineffective, with two-thirds of infected implants failing 5

Long-Term Management

• Include patients in a regular periodontal maintenance program to prevent peri-implant diseases 1
• Proper control of systemic diseases such as diabetes, cardiovascular diseases, and osteoporosis can help prevent periodontal problems and peri-implant diseases 1
• Smoking cessation is critical, as smoking is a significant risk factor that increases early dental implant failure 1

If symptoms do not improve within 7 days, or if irritation, pain, or redness persists or worsens, the patient should be re-evaluated for possible peri-implantitis requiring surgical intervention 6.
