Denture Complications

Direct answer
Sore spots appearing within the first 72 hours, denture stomatitis, inflamed hyperplastic flange tissue, angular cheilitis, gagging, burning mouth and progressive ridge resorption are the recognised complications of denture wear. Most arise from overextended borders, premature occlusal contacts, poor hygiene or continuous night wear, and management follows the same discipline: locate the fault with pressure indicating paste and occlusal assessment, correct it, and treat infection — candidal in most stomatitis cases — with denture hygiene and topical antifungals such as nystatin or miconazole.
What you must remember
- Traumatic ulcers appear within 24 to 72 hours at classic sites: buccal and labial frenums, canine fossa regions, mylohyoid ridge, retromolar pad and hamular notch — each corresponds to overextension or a rough border.
- Locate faults with pressure indicating paste (PIP) on a dry denture surface and relieve sparingly; occlusal premature contacts cause diffuse ridge pain without a visible border fault.
- Newton's classification of denture stomatitis: Type I localised pin-point hyperaemia, Type II diffuse erythema of the denture-bearing mucosa, Type III inflammatory papillary hyperplasia of the palate.
- Denture stomatitis is strongly associated with Candida albicans, continuous night wear and poor denture hygiene; treatment combines leaving dentures out at night, disinfection and topical antifungal therapy (nystatin suspension, miconazole oral gel).
- Epulis fissuratum (inflammatory fibrous hyperplasia) is a hyperplastic fold along a chronically ill-fitting flange; small lesions regress after denture correction, established ones need surgical excision with a reline or rebase.
- Angular cheilitis commonly accompanies stomatitis — Candida with staphylococcal involvement — and warrants checking nutritional deficiencies (iron, B-complex, folate) common in Indian elderly patients.
- Kelly's combination syndrome follows a maxillary complete denture opposing natural or restored lower anteriors: anterior maxillary ridge resorption, papillary hyperplasia, fibrous tuberosity enlargement and supraeruption of lower anteriors.
- Gagging may be patient-related (hypersensitive soft palate, anxiety) or denture-related (overextended posterior border, thick palate, unstable base) — treat the cause, not the symptom.
- Midline denture fracture usually signals a poor-fitting base flexing across the midline or a deep palatal vault with unbalanced occlusion, not merely "brittle acrylic".
The 72-hour review, worked through
At the first review, listen before looking: the patient localises pain with one finger, and that finger maps the fault. Seat the denture, dry it, brush pressure indicating paste thinly on the intaglio, reseat and have the patient press and rub; remove and read the paste — a pinpoint show-through spot corresponds to the ulcer and is relieved with an acrylic bur, a stone at a time, never blindly. If the mucosa looks normal and the pain is diffuse over the crest, think occlusion: mark the occlusion in centric and excursions on an articulator mounting or with articulating paper in the mouth and equilibrate. Inspect the palate for the velvety erythema of Type II stomatitis or the cobblestone papillae of Type III; check the flanges for a fold of tissue — the beginning of an epulis — and the commissures for cracked, erythematous angles. Every case of stomatitis gets the same triad of prescriptions: dentures out at night into a disinfecting soak, brushing of the prosthesis with a soft brush and non-abrasive cleanser, and topical antifungal for the fitting surface and mucosa. Arrange review; if papillary hyperplasia persists after the inflammation settles, it is treated surgically or by conservative tissue conditioning.
Beyond the obvious ulcer
The reflex error is to grind the denture wherever the ulcer sits, without asking whether the fault is a border, a bump or a bite: an ulcer over the mylohyoid ridge from an overextended lingual flange reappears if only the spicule is smoothed. The second error is prescribing antifungals for every red palate while the patient continues to sleep in the dentures — candidal stomatitis relapses until the reservoir on the fitting surface is disinfected and night wear stops, which is why examiners ask "why does denture stomatitis recur?" rather than "which drug?".
Frequently asked questions
How is denture stomatitis classified?
Newton's types: I pin-point palatal hyperaemia, II diffuse confluent erythema of the bearing mucosa, III inflammatory papillary hyperplasia (cobblestone palate).
Which organism dominates denture stomatitis and how is it treated?
Candida albicans, treated by denture hygiene and disinfection, leaving dentures out at night, and topical antifungals such as nystatin or miconazole gel applied to mucosa and fitting surface.
What is epulis fissuratum?
Inflammatory fibrous hyperplasia forming folds in the vestibule along a chronically overextended or loose flange; recent lesions regress with denture correction, established fibrous folds need excision followed by reline or rebase.
What is combination syndrome?
Kelly's pattern of changes when a maxillary complete denture opposes retained lower anterior teeth — anterior maxillary ridge loss, palatal papillary hyperplasia, enlarged fibrous tuberosities and supraerupted lower anteriors — demanding posterior support restoration.
Why do traumatic ulcers appear in the first 24 to 72 hours?
New dentures meet unconditioned mucosa over overextended borders and unrefined occlusion; the pressure concentrated at frenal and ridge prominences necroses the epithelium within a day or two of wear.
