A few years ago, Vandoren changed the way they manufacture their mouthpieces.
I believe our manufacturing process has become more consistent than before.
However, I feel that they wear out much faster than the previous models.
I used to buy a new mouthpiece every 10 months to a year.
Since the current manufacturing method was introduced, the facing curve wears down particularly quickly; in my case, I’m already considering replacing it after just two to three months.
I’m aware that because my front teeth are slightly crooked, one side wears down more easily, so I have to replace my mouthguard more frequently than most people.
Are there any of you who, like me, feel that your mouthpiece wears out faster since the manufacturing process changed?

What exactly is wearing out? I have been using the same Vandoren M13L for well over a year with no degradation of the facing that I notice. I use a rubber patch on the beak and play double lip, so beak wear is not an issue. Do the facing measurements actually change? What range of change are you finding?

I had switched to a BD2 as soon as it was available. Not really seeing any appreciable wear to the rails (both sides and the front).

I've used my 5RV since about 2000. Not sure what that says about me.
Before that, from about 1975-2000 I used the V360.

I've heard at least two well known mouthpiece makers/refacers say a pro would need their mouthpiece lay touched up after about two years use. The main culprit is rail tilt, which occurs at the fulcrum where the reed flexes as it bend to follow the curve of the lay when vibrating. I'm surprised when people say they've played a mouthpiece for years, decades even, with no wear.
It's evident ebonite wears, even through handling (ligature marks etc), so what's going on? Do lays wear, or don't they?
I use D'Addario Reserve Evolution mouthpieces, and I'd say they wear and need replacing after around two years (their cost doesn't make relaying worthwhile). That mouthpiece is also CNC, so I'm wondering whether CNC machining requires an ebonite with different characteristics to the older types, which were moulded. Of course, manufacturers would always claim the newer ebonite is much better quality and is sonically superior to their old one.

Yeah, my reeds last longer than my mouthpieces. Have to buy a new on every week. But I am travelling at near light speed relative to the rest of you. This message is from a distant galaxy in the future. Maybe I should just get a metal mouthpiece.

Thank you all for your responses.
I’ve attached a photo of the mouthpiece I’ve been using for about two months.
Can you see the shadow in the center of the rail, especially on the left side?
Please don’t mind that the shadow on the right is higher up than the one on the left—it’s just because of my teeth.
The shaded area here is where wear on the facing curve can be visually confirmed.
In fact, when you press the glass against the table and measure it with a thickness gauge, you’ll find that the starting point of the curve has become less pronounced or that the left and right sides have shifted since the time of purchase.
At the very least, the condition of the facing curve changes significantly from the time of purchase.
I felt this was particularly common with recent Vandoren machining, but simply realizing that not everyone shares that view was a valuable insight in itself.
This happens with any mouthpiece.
I experienced this issue when using Fobes, BEHN, and Zinner mouthpieces as well, but with those, I was able to use them without any problems for at least a year.

For me, the visual difference amounts to a "scuff mark." I have never found that to be an issue. However, if you draw the mouthpiece backward upon a piece of standard typewriter paper while tilting upward to accommodate the tip (light pressure and check after each iteration) that "scuff" will polish right out. But as with ANY polishing of ANYTHING with ANY material, you are removing very microscopic amounts of material. So don't do that too often.

As someone who still plays 100 year old mouthpieces, I obviously cannot comprehend your issue. Significant wear should take decades in normal use. I have to ask how you maintain your mouthpieces. Surely this wear is due to excessive force or abrasion when cleaning or swabbing. It seems like any wear caused by air, saliva and reed could not possibly have any significant impact for many years.

I assume you don't have pictures of the mouthpiece when it was new. I'd have to wonder whether the mouthpiece came that way.

First, let me clear up a misunderstanding: comparing the ebonite used 100 years ago—or even 30 years ago, for that matter—with the material used today is a completely pointless exercise.
This is because the manufacturing process for ebonite and the method used to shape the mouthpiece are completely different.
I know of an orchestra musician from the 1900s who played his entire career using just one mouthpiece.
Of course, the mouthpiece must have worn down, but I don’t think it was as noticeable as it is today.
With that in mind, I want to discuss whether Vandoren mouthpieces these days tend to wear out easily, so bringing up older mouthpieces is missing the point.
So, regarding cleaning, I try to be as careful as possible.
Basically, I don’t use swabs and I never touch the facing.
If calcium deposits build up, I use lemon juice to remove them.
I don’t have any photos of the item in new condition.
But do you really think there are people stupid enough to buy a damaged item every single time?
If it had been like this from the start, I wouldn’t have bought it.

You have to remember, that these days, manufacturers don't make anything to last. Quality standards have deteriorated. With large mouthpiece companies part of the discussion around a new model will be its longevity. It's not in the interest of their business for it to last.
The older 'forever' mouthpieces mentioned are no longer made.
I'm sure some players will experience more playing-based mouthpiece wear (as opposed to wear by handling) than others for a variety of reasons. For example, the lesser pressure (supposedly) applied by double lip players would, presumably, cause less wear. Assymetrical emboucher, must also potentially be a factor, as with S.Takuto.
