Your situation should be close to the picture, light or heavy. But this is not the key, because enamel hypoplasia will get worse with time. Enamel will fall off with chewing and calcification until symptoms of pulpitis appear.

So I suggest you repair it as soon as possible, and don't think about it after the pain appears. This will be very troublesome and will affect the service life after maintenance.

Nowadays, porcelain crowns are generally considered for restoration.

Porcelain crowns have many prices, and the material is the most common at present.

1. Nickel-chromium porcelain? 250-380? Advantages? The price is relatively cheap. Disadvantages: Some people will have symptoms of gum blackening after using porcelain for many years (years of clinical experience).

2. Titanium porcelain? 500-600? Advantages? The price is moderate, which can avoid the problem of gum blackening. Disadvantages: titanium volatilizes a lot in high temperature processing, so the content is very low. As an industry secret, it is generally not told, so the real effect may not be completely guaranteed.

3. Chromium alloy (recommended)? 700- 1000? Advantages: bright teeth, good color, lifelike, good compatibility with human metal, no gum blackening and other problems. Disadvantages: the cost is relatively high, and the economic conditions are generally not easy to accept.

4. All-ceramic and crystal porcelain? 3500-4500? Advantages: no metal inlay inside, high tooth fidelity. Disadvantages: low strength, high requirements for the patient's abutment (the landlord's situation is not suitable for this restoration, so I won't elaborate)

You should be very clear when I say this. The answer is purely manual and clinical without reservation.
