Many meanings of 'Krone' (crown) share the idea of the uppermost part or highest point of something: on a king's head, on a tooth, at the top of a tree, or on a wall.
Vom Gipfel des Berges, der Krone der Region, hatten wir eine tolle Aussicht.
From the summit of the mountain, the crown of the region, we had a great view.
You can recognize the dental meaning immediately from the context. Words like 'Zahn' (tooth), 'Zahnarzt' (dentist), 'Backenzahn' (molar), or verbs like 'bekommen' (to get) and 'einsetzen' (to insert/place) are clear signals.
Der Zahnarzt hat mir empfohlen, eine Krone einsetzen zu lassen.
The dentist recommended that I have a crown placed.
When 'Krone' (crown/krona) refers to a currency, the plural form 'Kronen' is almost always used, together with a number.
Ein Kaffee in Kopenhagen kostet etwa 50 dänische Kronen.
A coffee in Copenhagen costs about 50 Danish kroner.
In the abstract meaning of 'monarchy', 'die Krone' (the Crown) is often used in political or historical contexts. A typical expression is 'im Namen der Krone' (in the name of the Crown).
Die Kolonien wurden von der britischen Krone verwaltet.
The colonies were administered by the British Crown.
The idiom 'die Krönung von etwas sein' (to be the crowning point of something) or 'etwas die Krone aufsetzen' (to top something off) refers to the climax or conclusion of something, often ironically for something especially negative.
Erst ging mein Auto kaputt, und als Krönung des Ganzen habe ich meinen Schlüssel verloren.
First my car broke down, and to top it all off, I lost my key.
In connection with a monarch's headpiece, the verbs 'tragen' (to wear) or 'aufsetzen' (to put on/place on) are usually used.
Die Königin trug bei der Zeremonie eine wertvolle Krone.
The queen wore a valuable crown at the ceremony.
bridge
'die Brücke' and 'die Krone' can both come up at the dentist's, so they are easy to confuse. A 'Brücke' (dental bridge) replaces one or more missing teeth and is attached to neighboring teeth. A 'Krone' (crown), on the other hand, sits like a cap on a single damaged tooth. So if a gap is being closed, 'Brücke' fits. If an existing tooth is being protected or rebuilt, 'Krone' fits.

Die Zahnärztin setzt Finn eine Krone auf den beschädigten Backenzahn.
The dentist is putting a crown on Finn's damaged molar.
Nach dem Unfall braucht mein Vater eine Brücke für die Zahnlücke.
After the accident, my father needs a dental bridge for the gap in his teeth.
