If you are thirsty after brushing, choose plain water. Plan your usual bedtime drink before brushing and skip the immediate rinse at the sink.

Waterpik recommends warm water for its flossers. Check your own model and use comfortably lukewarm water if cold water feels sharp.

Let an intact handle return to room temperature before you consider charging it. Check your manual and watch for signs of battery or housing damage.

Lift away the paste, check the care label, and use cool water on washable fabric. Here is a quick approach for a fresh spot.

Turn the brush off, then check the fit, the connection, and the condition of the head. A second compatible head can help you narrow it down.

Look for a clean, rigid container with a secure lid and keep it with your belongings. A napkin on a lunch tray is easy to clear away.

Check the care directions for your clear retainer. Clinics give different instructions, and the right cleaning method depends on the appliance you received.

Try a gentle rinse first. If the hull sits between teeth and floss moves freely, make a careful pass and stop if it still feels stuck.

A tight gap or rough edge can catch floss. Notice where it snags, keep the movement gentle, and find out when to ask your dentist to check.

Your first sip can taste sharp after brushing. Here is what may be changing and how to make breakfast taste like breakfast again.

Water that leaves a dental unit is not sterile, and it has not been sterile for decades. The narrow tubing that carries coolant to the handpiece and the air-water syringe provides an ideal surface for a biofilm that sheds organisms into every patient's mouth. Sterilisation of the instruments does...

A young adult presents with soreness of the gums, and the examination shows a striking change that is easily mistaken for severe periodontal disease: the mucosa is thickened, folded and studded with tiny yellow pustules that rupture to leave shallow ulcers resembling snail tracks. This is pyostom...

A patient who becomes cyanosed minutes after an apparently routine infiltration, yet keeps talking and breathing comfortably, presents a diagnostic trap. The saturation monitor reads in the eighties, supplemental oxygen changes nothing, and the chest sounds clear. This is the classic signature of...

Most patients with clicking, locking and jaw pain improve with reassurance, soft diet, splint therapy and physical measures. A minority do not, and their imaging shows a displaced disc with degenerative change, a shortened condyle or a persistent closed lock. For that group, two operations compet...

A slowly growing palatal swelling that the patient has noticed for two years, a minor salivary gland tumor that looks deceptively well demarcated, and a nerve that carries tumor cells far beyond the visible mass: this is the natural history of adenoid cystic carcinoma. It is uncommon, it is rarel...

Saliva is easy to overlook until its volume changes. An excess produces drooling that soils clothing and isolates a patient socially, while a painless enlargement of both parotid glands raises the question of systemic disease. Sialorrhea and sialadenosis sit at opposite ends of the same physiolog...

When caries in a primary molar reaches the pulp but the tooth can still be restored and the supporting bone is intact, pulpectomy offers a way to keep the tooth comfortable and functional until exfoliation. The procedure removes both the coronal and the radicular pulp and replaces it with a resor...

Disorders of the fibroblast growth factor receptor genes produce some of the most distinctive facial appearances in medicine, and the two extremes are instructive. Pfeiffer syndrome allows survival with staged craniofacial surgery, while thanatophoric dysplasia is almost always lethal in the neon...

A panoramic radiograph that shows a uniformly dense mandible or maxilla can indicate an entirely benign finding, such as a dense bone island or a torus, or it can be the first clue to a generalized skeletal disorder. Osteopetrosis and the broader group of osteosclerotic conditions differ greatly ...

A patient who cannot open the mouth more than a finger breadth, yet whose temporomandibular joint still moves on imaging, presents one of the most easily misdiagnosed problems in oral surgery. The restriction in such cases lies outside the joint, and the condition is termed pseudoankylosis. An el...

A lateral cephalometric radiograph is only as useful as the analysis applied to it. The same tracing can be read as a skeletal discrepancy by one method and as a dental compensation by another, and the conclusions reached about extraction, surgery or growth modification may differ accordingly. Un...
