De meeste patiënten die voor facings op de voortanden kiezen, doen dat om een gelijkmatiger gebit en wittere tanden te verkrijgen. Maar: te wit en te recht geeft een onnatuurlijk aanzien van de tanden en valt op. En dat willen patiënten nu juist níet. ‘Het moet mooi zijn, maar het mag niet lijken of ik kunsttanden heb’, hoor ik vaak. Zowel voor de...

Er gebeuren heel wat ongelukken in de zomer. In Drenthe (waar ik woon) zijn trampolines erg geliefd onder de kinderen, maar die veroorzaken wel veel dentale trauma's. Ook skaten, zwemmen en fietsen kunnen lelijke fracturen veroorzaken. De tandarts moet dan de juiste beslissing nemen als het gaat om de vraag hoe de tand weer effectief en esthetisch...
