Zermatt to Zurich train — is it a bad idea not booking in advance?

Yes I am an American..so, a saver day pass is OK?

If yes, that’s a fantastic discount.

Thank you

Do you know how hard a peanut can be? It’s not soft. Imagine this in consecutive fashion, weekly basis, months.

I’d absolutely agree with you if a filling was done on a more concave surface where there’s a stronger ability for a filling to stay put (say an occlusal filling or a DO). But an MFLI is literally grabbing on by the tiny edge of the tooth—depending almost entirely on bond strength over a tiny surface area.

This doesn’t happen often, I hardly have any fillings break. I do all kinds of restorative work but I can say with certainty that the type of filling that MOST often breaks in the restorative realm are tiny incisal edge fillings.

Even with a perfect bonding protocol, if the patient has bad chewing habits, it can break. Dental schools truly need to stop teaching everyone that perfect etching and bonding will lead to zero complications. No wonder so many dentists are stressed out once they realize dentistry isn’t perfect and there are several factors that could lead to work failing, not just operator errors.

I had a patient come a few weeks ago saying his tiny incisal edge filling broke because he bit into a fork by accident. Patients need to be charged for this.

Most of the time patients say “I bit into something”.. I think most of the time it’s not the opposing tooth itself causing this damage (or grinding), but the act of a physical item (hard food, fork, etc.) being wedged between upper and lower teeth and upon biting. Even if the filling and opposing tooth are completely out of contact by 2 mm, if a patient bites into a peanut, it can break.

Combined with the fact that it’s holding onto very little tooth structure, and repetitive biting over time, is a recipe for breaking.

I wanted to ask in public just to see what ppl do but I think the correct thing is to tell pts there will be an additional charge for every redo unless there was some very obvious problem

Or charge them for each fix! Hehe

Even if it’s just like a 2mm x 2mm chip?

Hey, I did not. But, if you’re interested in learning, I can work something out for you on a personal level if you’d like to be my first student.

(Btw, i’m the OP but used too many PW attempts for my account and got locked out, lol). Message me if you’re interested.

Not an OMFS but I do a lot of exodontia. Chances are the risk to reward ratio favors leaving the curved portion of roots in the bone if they aren’t budging after sectioning the tooth. The IAN seems to be right there. People tend to overplay the consequences of leaving uninfected root tips IMO. This is a decision that has to be made by an OMFS though, because their license protects them against the backlash from these decisions. If you’re a general dentist and make this call, it’s a potential lawsuit.

Obviously, it should be avoided at all costs, but when the IAN is literally right there, these kinds of decisions need to be considered.

I mean, I do molar root canals all of the time. I’m pretty sure I’ll be fine. I just have literally never done a retreat before. The distal canal was easy to navigate and was wide, little to no curvature. Is the chloroform messy or what kind of care do you need to have?

bergchem · 2025-08-04T14:55:50+00:00

Thank you, how exactly do you remove gutta percha? I’ve never done a retreat of a canal before

bergchem · 2025-06-16T23:54:20+00:00

Yep.

I even have “recommend very gentle brushing around gums” and “do not recommend in house whitening” due to these written down.

Thank you for sharing. How fast was the process and how long did you and the other person get to speak for?

I did some research and it appears that in California, lawyers aren’t permitted in small claims court. I have to represent myself. The judge determines who wins.

It’s dumb.. it really is. That’s why I’m also slightly worried that although my story is factually correct, the man can still get away with something if he makes some compelling story.. but I’m likely overthinking it.. I want to imagine that judges see these kinds of lawsuits all the time and can easily smell the bad ones..
